Which Heads? Im having trouble choosing between stage 3 livernois heads and Trickflows. I have the money for the trickflows but dont know if its worth wasting an extra 600 dollars. My car is going to be a stalled automatic N/A car for the street/strip set-up with a 228 to 230 duration cam. Is it worth the thicker deck and all, I mean Im not going to be adding nitrous or any other FI? Ive seen stalled automatics put down almost the same numbers as the aftermarket heads.

I say afr 205's that Tony has touched (custom porting to unshroud the valves). We call that Mammofication brother. Its a little on the pricey side, but you get what you pay for. Tony really is a master at making power with AFR 205's. I reused my afr 205's from my 346 that made 490/445 @ wheels, on my 402 they made 511/500 @ wheels. (Same h/c and all boltons from 346 were re used on the new 402) Sorry just a little biased towards AFR's. Not saying Trickflows aren't great, because they are great, but you need different rockers from what I am told, and to me thats just extra money that could've been spent on the Afr 205's and Tony's magic.

Yup untouched other then being milled to roughly 58cc's. If I had the cash to have had Tony Mamo open up the bore to 4.00 and unshroud the valves I probably would've made another 10+ rwhp. Not bad for a 205 intake runner.
