Better heads worth it? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a reman 350 in my truck. It has 71 350 76cc heads on it. I have no idea what the cam is but I assume it’s a stock cam. Is it worth swapping to a set of aluminum 64cc heads? I know a cam swap would be ideal but I am afraid to do a flat tappet these days and I think if I’m going to put the money into a retrofit roller I might as well just get a crate engine. I also have an edelbrock eps intake and summit headers. Any thoughts or opinions?

"Worth it" is a very individual value judgement. You will definitely notice a difference in the seat of your pants.

Cam, heads and compression makes power. So putting on good heads will get you more power. But the motor is almost torn down enough to replace the cam, why not do both? Use break in oil for the cam.

double tap

Do the 64cc heads have accessory mounting holes in all the right places? Assuming yes, other then the labor, the need to buy parts count for a head swap is pretty low. A top end gasket set and maybe a head bolt set(depends on your thoughts on reusing head bolts).

What is the planned use for the truck? Possible the higher compression might need more expensive gas.
