I've thought about the AFRs, but I don't know if there worth $1400. There seems to be some good times coming from the corral with those heads, but most of those guys have custom cams and lightly ported (gasket matched maybe) intakes.
What do you guys think of the Brodix ST 5.0 heads? Awile back 5.0 got 20 - 25 rwhp out of an otherwise stock mustang. With intake and exhaust (along with the little stuff), I don't think 40 rwhp would be out of the question. Plus you wouldn't have to buy new rockers or pushrods.
On another note...With aftermarket heads, which valve would be closer to coming in contact with the stock piston with an aftermarket cam? For example, with a 1.90 - 2.02 intake and 1.60 exhaust valve which one would be more likely to hit as far as p/v clearance goes with a single pattern cam?
Btw, thanks for all the replies.
