What heads to go with????
my current vehicle is a pearl white 87 iroc-z. i have a 350 thats getting ready to go in it but im wondering what heads i should go with?
its a 4bolt 350 out of a 73 z28
bored .30 over
flat top hypereutectic pistons
and its got a 500 hydraulic lift crane cam with 302 duration (246 @ .50)
i have a set of 291 double hump heads with the 2.02/ 1.6 valves, but a few people have told me the cam is too big for these heads so i was wondering if anyone on here had any idea what heads i should get to make good power with this cam??????
thanx caleb

A lot better than the double humps, but pretty big heads. You'd need to spin a 350 pretty tight to use all of them.
195's with 2.02/1.60's would make more sense.
(By the way, it's .030" over, not .30" over)
