Don't do it.

 

Please support the recommendation.

 

do what? use a china cast head on a engine with china forged rods , crank and pistons ? :lol: there not the pro comp #### everyone complained about and the valve train/ hardware I am using is used in many US cast heads. these are better then the x303 and performer rpm castings I've had in the past, there pretty decent as cast and will take pretty much any port a dart pro1 head will...... Like said they all get lumped in with the old pro comp ####.

 

Many do it. Ls community seems to have less hate about the Chinese heads.

I’ve never used a set, but someone can donate me a Chinese block, Chinese stroker kit, Chinese heads, Chinese turbo, Chinese fitech.... I’ll figure out how to go fast with it.

 

Can you post pics of the heads?

I'd like to see them.

 

there a dart clone don't have any of the set I have, those sitting in a buddies shop getting grinded on, here's some I found online private labeled as blueprint, there on ebay under a few names, lots of parts houses selling them or just get them from the source.



china intakes for the most part are still #### procomp sand castings, haven't looked for a sbf efi intake in while, Have a couple laying around. Not sayng all china castings are good... saying some of the stuff is impressive for the price, like these

 

I bought a Chinese intake, (just to seal up an engine) one of the front intake runners was 3/4" off alignment! Nice quailty huh?

 

I got a friend who built up a Nice 306 with Procomp heads 190CC.

306 bored out with pistons 11:1 compression
Eldebrock Victor Jr Intake
Procomp 190cc heads bought on ebay for 600$ Shipped. Untouched bolt them on out of the box.
TFS Stage 2 camshaft, Those heads require max .550 Lift with the springs, so the tfs stage 2 cam fit the bill.
650 Holley DP Carb

On a engine dyno it made 368HP at 6550 Rpm.

 

and here is some sve and possible promaxx being die cast I found while looking for info on all the imported heads showing up. Some nice equipment in that foundry.

Hard to find info on the promaxxx sbf head, summit and jegs still show a pic of afr clone while the rest show an eldelbrock based casting

 

It's easy to find info on ProMAXX. What do you want to know?

Jason has his own castings (from China), everything else is done in Alabama.

Heads flow what they flow, and everyone copies everyone.

 

I've heard good things about the Skip white heads.

China castings but with Comp Cam parts.

 

I’m in. Lol I’d throw a set on mine too,if they explode I’ll get another junkyard motor and try again. I know a guy locally that has experience with no name heads on his car. He beats the ##### out if it and it’s still going. I just think the quality control is bad as far as china stuff, that’s the chance you take. Some have great experience and others fail out of the box. It’s like going to Vegas, you might win and or you might get herpes. Or Both lol

I was looking at those as well, just haven’t pulled the trigger. if you can get it with the eBay coupon they would be well under 700$ shipped

Cheap parts have always and will always be around. There is too large of a market to ignore.

You get what you pay for......both here in the US and in China. Ford has parts from China. So do pretty much every manufacturer. Chinese manufacturing is a fact of the modern economy. Just as there are shoddy manufacturers in small town (even big city) USA, there are shoddy manufacturers in China.

China wants money. They make a part to spec. If the company that had those parts made isn't doing a secondary QA process upon delivery and just sells them, they get what they deserve. But if they do QA at delivery and too many itemms hit the failure point, the buyer can say "I'm not paying." And reject the entire shipment.

When that happens enough China quality will rise. This is basic stuff. Japanese products were total poop after WWII. Now their quality rivals the best in the world and surpasses many. Unless you don't want to pay for it. Same thing is/will happen with China.

That said I have been reading about ProMAXX heads.... Looks like China casting with finish assembly here.

 

On the ProMAXX heads, all the machine work is done here also.


And their part number "system" is........odd.

 

easy for you, your in the trade. I'm well aware everyone copies everyone. I haven't seen any promaxxx out in the wild myself for a SBF. bbc and sbc but not sbf. Just general experience with them, What casting there now selling in the three version they offer the head in. They changed the casting based on the stock photos I'm seeing from places selling them, hell those might even be the old patriot castings Marty had before promaxxx bought it, one is based off an afr head, even CHP site still shows it, the other on an edelbrock layout that looks like the unfinished castings in the picture I posted.


I saw a recent china casting that looks real close to the most recent afrs, same port layout, deck and chambers talking about a 185 and 210 as cast head but they only had the sample set.

Might be the old Patriot castings? Considering Jason bought Patriot, and Alabama Cylinder Head......I'd say that's a reasonable guesstimate.

And it's easy for you, too.

We are a family owned business that began in 2012 by purchasing the remnants of Patriot Performance and Alabama Cylinder Head Exchange.

 

Local guy got almost 400cfm out of a set of those chinese cleveland heads, ported of course.

 

just under 700hp on PUMP GAS 400ci street/road ra eng using fps/avg xtc B3 type port budget Clev heads way back in 2010 ...

:salute:...Home page... :salute:

Not me. I just decided I needed to add some heads and I've always found Jason, and his Dad, to be straight up people. They can make copper wire out of a penny, but they've always been honorable.

I might add some others........and I might not. I'm tired of some of the companies........antics.

 

I didn't think it was you but noticed them on the site. Was curious is all.

 

They started with the Patriot casting, then redesigned it in house (the Ford port was designed by Keith Kraft) and used a different manufacturing process than the original head. The finish is quite nice.

I've been adding them to the site for the last couple of weeks.....because I do things in the longest, most tedious, method I can find. I've never been big on selling heads, outside of engine builds, because no one makes money on cylinder heads. As far as flow goes, you need X flow for X power....I really don't care who's name is on the head as long as it hits the number and doesn't fall apart.

As far as what they look like. You take the factory valve angle and location, add the factory dimensions and accessory mounts and how different can it look? Besides...once you clowns add nitrous, blowers, or turbos......or nitrous and blowers and turbos..all you really need is a giant hole to stuff air through....

I don't much pay attention to the flavor of the week stuff. If the customer wants 525 on the motor I'll just give him a head that will allow 525 on the motor.

Also.....I wouldn't put a ProComp head on a motor any quicker than I'd marry a porn star and expect her to not cheat. I wouldn't trust them to be reliable scrap aluminum, for that matter. Troy at FPS is working on his APE Cylinder head program, he's been threatening to get me the info on that for about three years, but I haven't seen it yet. But, if he ever gets it rolling, I suspect it will be a decent piece. I like AFR and TFS fine, but I'd rather not deal with either company if I don't have to. I go back with AFR to when Ken bought Brownfield, and I went back with Brownfield farther than that.

I don't know anything else about the other Chinese based heads, except EPA regs are making it more and more difficult to cast anything in America.....and that jacks the cost up as well.

 

".I wouldn't put a ProComp head on a motor any quicker than I'd marry a porn star and expect her to not cheat."

:lol:

 

This is the one I was talking about seeing on facebook, they posted some more info, its from Track Boss Products facebook page. and they got 465 HP 435 TQ on a as they put it "347 Econo build"

60cc chambers
185cc intake
8mm valve stem size.
2.02/1.60 valve sizes
saying $775 bare and starting at $950 complete.


If its as decent of a casting as the pro-header heads I got that would be a nice budget head to play with.

 

Those look different than what I received from Pro Header...

 

ED I have the same head you just posted.... the one's track boss has is a tweaked afr clone. these look new, I have not seen them anywhere else.

btw you got a valve package for the pro header one's yet? need to find a locator for the lunati spring I plan on running.

Yup - I asked Terry about these castings on the "8.2 Deck Nation" Facebook group but he was very vague.

Looks like a hybrid of a stolen AFR 185 and Victor Jr casting from the pictures. Got enough raw castings here to do some comparing.

The Pro Header is definitely a DART clone. I like the design but it's kind of dumb they also copied the DART 11/32" valve stem arrangement. Would like to have seen 5/16" or 8mm in a new design casting. A buddy of mine is still working on the old Canfield 18 degree Ford head with relocated valves, offset rockers (ala LS3) and completely redesigned runners but his HEMI business is just too busy to concentrate on another new project.

Still going to do up these Pro Header castings and sell them at a deal to someone, but here's hoping someone will eventually get these overseas castings containing every modern feature included...

 

If it's a budget build and gets you from point A to point B it doesn't matter. I rebuilt my step-sons 2003 Buick Regal with mostly Chinese parts from eBay and it runs just fine.

 

So is there a clear front runner in the quality and flow per dollar in the Asian head category. Flow alone doesn't do much good if they fall apart or you have to spend big bucks at the machine shop to get them able to use.

From what I have seen so far I personally would be more inclined to go with someone like Promaxx vs Ebay for the simple reason that someone has put the money and work into building a brand name that they presumably want people to think about in a positive manner. So you would hope they do a little bit of QC before they send them out to a customer.

If you are selling on Ebay you might be selling a very similar head but you haven't put any money or effort into the goodwill of a brand name. If you get a bad reputation just open up shop under a new name and sell the same stuff, repeat as necessary.

I would add one more thing to this discussion. The bare RHS heads can be had pretty cheap and while I have never owned one I hear they are a good quality head with very good potential ported.

 

I know of two credible builders who use affordable foreign heads. One builder uses RHS bare castings and tweaks them to his liking. He is the type of builder that treats every build as if his own. Very meticulous.

The second builder has the build ethic of the first and uses ProComp heads in high dollar builds. He buys the bare castings and builds/ports to suit. He swears by the casting quality and has no problem tossing them on high HP boat engines. He showed me a ten year old BBC set that just came in for their first re-freshening. If you know anything about competition boats; you know the torture they go through versus an automobile engine. A pair of custom ProComp heads for a sbf is just over $900.00. I'm talking high quality parts and 5 angle valve jobs. Considering that my new AFR heads had a major machining flaw and and valve guide issues; I might be tempted to use RHS or ProComp castings on my next build. (AFR did make good on my heads and offered superior customer service.) I think that counts for something.

 

Rhs is Chinese?

I thought they were New Zealand when pro topline and rhs/comp bought them and they now cast in China?

 

Still New Zealand last I heard,,,

 

DEALER-Steven performance cylinder head


wonder what castings they are suppling to summit and jegs… guessing mostly BBC/ SBC STUFF but this is where the Sve heads come from.

Jegs also has the Proheader dart clone sbf casting now under the RPC brand.

 

I just looked and didn't see any proheader or RPC heads on jegs. I could be missing something since Jegs is the worst organized website in the world.

 

Interesting link.

 

they don't make it easy to find, must be new on the site since no real info listed.
