My car is an 85 Vette with cast iron heads. They only gained another 5-10 HP in the years up to @ 1990 and then went to the LT-1 motor which was improved from the L-98 that I have.

So I have flat top pistons and a flat tappet cam. I want to replace he heads and cam. My goal is 300 RWHP. Basically a hi-12's car that is streetable.

The aluminum heads I have been looking at are 190CC with 2.0-E and 1.6-I valves.

My real question is, dont heads with the same numbers flow the same, cast iron or aluminum?

If I could save some money on the heads I would go with a roller cam setup with the xtra money and gain some HP there.
