Head Selection - Question
I recently had the following mod's completed on my 04/A4:
Comp Cam 233/239 .588/.595 113 lsa
Underpulley
160 degree thermostat
Dynatech Supermaxx headers w/x-pipe
Corsa Touring
Vararam
3600 Yank Converter - Cooler
3:73 Differential
Tune
By the way, based off of my previous questions concerning the above, the forum member here "steered me" in my selection of these modifications.
Question I now have; I would like to put a set of heads on to compliment the cam and the rest of the mod's. What is your thoughts on head selection along with throttle body? Is the Fast 90 worth the addtional h.p. as well?
By the way, I made 385 rwhp and ~365 rwtp on a Mustang Dyno with the mod's so far. I believe on a DynaJet I would be around 400-410 rwhp. With the heads/T.B. what additional h.p. do you believe this will make?
If you would, please explain why you prefer a certain head.
Thanks

You can't go wrong with either AFR or TFS heads! But both are pricey. Patriot makes a decent head. And the new LS3 heads are phenomenal for stockers.

AFR's 205's w/62cc chambers ported with fast 90/90 with 30 lb injecters. or I've herd of a 100mm intake i think from weiand in that case use a billit tb 100mm with 30 lb injecters. I dont know about that cam but the stock injecters may not support all that go fast stuff. Your set up sounds just like what I have planed for mine all i need now is the heads cam & intake...

I love the ETP's if you are willing to spend the money, we put a set of 225's on the motor we built for my wife's FRC 346ci 10.75 compression fast 90-90 with a cam not much more aggressive than yours and made 490 RWHP
