If you haven't already bought/ported your heads, look at the Twisted Wedge head specs done by Brian Tooley at TEA, www.totalengineairflow.com

Brian's stage 1 TFS TW heads flow 300+ cfm, with, more importantly, outstanding low and mid-lift flow. Read, BIG power with a streetable cam. He knows how to make these heads dance. You might end up with more performance for less money here; the stage 1 version is a very good head for a street/strip 331. AFR 165 or 185 heads could give you "close" to this custom-ported performance level for a little less money, out of the box. The ported TW heads would be best if you like them, and can afford the extra $$.

To give an intelligent cam and intake recommendation, we'd need the car's weight, transmission type, stall speed if automatic, rear gearing, compression ratio, header size/length, and REALISTIC intended use of the car. Also tell us which of the above factors you'd be willing to change or modify. Then, we'll try to help.

If you are refering to the 185cc heads as the Stage 1's they must be similar to the old stage 2's. These are the flow numbers for my TW stage 2 heads done by TEA.

Lift Intake Exhaust
.100 66.7 51.6
.200 146.9 110.8
.300 222.4 157.2
.400 270.5 196
.500 300.5 221.9
.600 304.5 239.5
.700 306.1 248.0

This is what I am gonna use to top off my 331.

You're right. I went and looked at TEA's web site; it appears that they've stopped using the stage 1, 2, and 3 designations. Don't blame them; it's very inaccurate to try to compare "apples to apples" across different vendors with these "stage" designations, and there's been some abuse of the terms (and some plain, poor workmanship) by a few vendors with little expertise and a big desire to make some bucks. That hurts the really top notch shops, whose stage 1 products will often out perform another vendor's "stage 3" product.

TEA is now doing mostly CNC programs for these heads, rather than hand-porting. They sell the "as cast" TW heads which are 170 cc, then three different degrees of CNC porting which deliver 185cc, 195cc, or 205cc. I was thinking about their first level, 185cc CNC program, which made me say "stage 1..." see how confusing the "stage" thing is?? Anyway, those 185cc port CNCs do indeed look very much like your heads specs. See them here: http://www.totalengineairflow.com/products/fordhead/ds_tfstw185.htm

With the right supporting combo, these heads should rip at higher rpms on your 331!

Well these heads are the reason I built a 331. Was orginally gonna be a mild 306 :eek: . Heads flowed too well. Decided to go with a high compression solid roller 331 :D

331, 13:1 compression, Comp Camps .672/.672 260/268 106 lobe sep, Super Vic intake. What ya think :D

BTW found my flow sheets and update the flow specs up to .700 Things are still climbing on the exhuast :eek: kinda leveling off on the intake but still gradually climbing.

.700 306.1 248.0
Even with the very long duration cam, the large amount of total lift to be achieved is so great that the valves won't be at those very high "altitudes" for very long; especially at the high rpms dictated by the valve timing. The excellent low and mid lift numbers of your heads should really help with the cylinder filling at those high rpm levels, as well as help to mitigate some of the loss in cylinder pressure in the mid-range. The compression should add to that effect. Should run great.

Wow...thanks for the respones...keep em coming...looks like a stage 3 (or now 205)would be serious overkill and all I'll need is the 185. Thanks guys....also how much do the stage ones run. Derrick

Ok Steve,
Here is the nitty gritty on my stang.
Weight-not sure but it is a well optioned notch-a/c
t-5 tranny
3.55 gears-good for nos
stock compression-thought i might increase this to 10.1-still want to use pump gas
headers equal leng shorties 1 3/4

Thanks for helping!!
