Check out the ported edelbrock performers in a recent post. Great value.

 

I believe those are sold.

 

Pending. If it falls through pay the man for some really good heads.

 

nobody?

 

Scarce commodity right now. Even gettting some new ones is a challenge right now.

 

The Promaxx heads are very popular. This site says they are in stock:

I’d rather spend the extra 200 and wait for new trick flows or buy the 55cc brodix st5.0 Heads.

 

I’ve heard good things about the AFR Enforcer heads. I know they are off shore castings but with good valve train

 

I have a set of Tw 185 for sake

 

 

 

How much are you asking and location? Can you give me details? Mileage, any issues, pedestal or stud mount ?

 

In my opinion used parts are worth 1/2 of new - i advertised used heads with new valves springs retainers keepers valve job & ported for price of one new head - had 2 questions one buyer that did not try to low ball - he's happy I dont have unused heads on the bench the earth keeps rotating...

 

And you have the correct view. Too many people asking for 90% of what they were new. Unfortunately it’s the market of people buying them trying to save every penny until they realize they end up spending the same as a new set. The cycle repeats and the market stays up because people will keep trying to save no matter the long run cost. There is nothing wrong with buying used parts but it needs to be an educated purchase with the knowledge of a risk. That comes in the form of a monetary decrease in value. But most of the times that’s not how it plays out.

 

Did you find a set of heads how much are you looking to spend. What king of valve spring are you needing solid or hyd. Roller.

 

I’ve had a couple people message me but waiting in details or price. I’m using a TFS 1 cam. What do you have.

 

Are you willing to take used heads to the machine shop to have them inspected? The Promaxx heads use PAC springs and quality undercut valves. Guys are boosting the crap out of them. The fastest stock block 302 in the country runs their 210cc Shocker Series head. The castings are done overseas and the 5 angle valve jobs, blending and assembly are completed in the US. Guess were they are located?

I have a pair on my turbo build. Just saying...

 

Fasterthangas do you have some for sale?

 

Nope. Just giving you a less expensive alternative that doesn't require an inspection or further cost to freshen them up.

 

I am willing to buy heads that need to go to the machine shop for the right price.
It’s extremely common to see people asking very close to retail for used parts. It’s always baffled me.

 

Yyyup, adds up quick - bought used aluminum SVO heads for $475 bought new valves for $190 - valve job & planed for $210 got lucky with springs - ported them myself - now have $875 plus my labor in them - are they worth it ? Probably not but they will work for my application...

 

Is this a stock shortblock? Stock pistons?

 

.30 over 302 roller block with Probe Forged pistons ( in line valve). So a basic OEM style rebuild.

 

Skip any head that isn’t 20 degree. Try to grab some afr heads or just go for the brodix with 55cc chambers. Will be perfect for just a basic build without outrageous expectations.

 

I appreciate the replies I have been down this road may times and all clearances will be checked (and double checked). But just for information purposes here are the piston specs

Are the pistons in or out of the hole?

 

You’re also trying to explain this to someone who knows what they are talking about. Look I’ll admit my probe comment was a little too vague but I know what I meant by it I shouldn’t have assumed others would. I apologize for being defensive. My whole point was gasket thickness and quench is up to him not me or you. As are a lot of things with his build. He hasn’t given enough info so all I did was make a head recommendation based on what he said. The whole piston and quench argument is stupid. We are both saying the same exact thing in two different ways. Let’s let it go and get this thread back on track.

Agreed. My main concern was he may take wording the wrong way and make a misinformed decision.
I have to ask; why a 20° head?
TFS heads offer better ptv clearance and have proven to work very well with a stock bottom end and Ed's cam. That is; if the OP's pistons play nice with the combo.

 

So based on all that.... Do either of you have any heads you want to sell me?.... Just Kidding, couldn't help myself.... So what I have learned through this is that people are asking a premium for used heads... very little off the new cost

You can find some used heads, but rarely will they be a great price, as you have seen. There were two sets here within the last three weeks that were great buys for a mild build like you have. One was a ported Edelbrock head that sounded ready except for possible spring change, and those flowed 258cfm(a bunch for that level of head). The other pair were TFS 170s, about $750 IIRC and sounded to be in very good shape. Deals like those pop up a few times a year, but they almost always need $200+ more for checks or new springs etc.

So figure costs to be near $1000 total if you find a good used head deal, or $1500+ for new top brand heads. It looks like bargain new head prices for lesser heads to be near $1000, give or take depending on spring needs. That's not cheap money in any way, so a stock GT40 head doesn't look bad, until you see the low flow specs(190cfm or under).

 

GT40 Y303 ported 20 miles since out of the box

 

[QUOTE="tommyad1919, post: 18666980,

Any flow data? And info other than ported?

 

I like the number of boosted engines they had in that, with near or over 600hp. I need their luck with building engines that survive. I hope to find out what a bone stock Explorer 302 will take, not to the level they went to, but maybe 9psi if I manage to get it done.

 

That's a great video. I'm doing a stock short block and cam with Promaxx heads and the old Performer RPM intake. Turbo is a custom built Garrett. I have high hopes. We shall see.
