Anyone ever try GM Alum heads
I was thinking maybe a set of casting #12363390
I know a guy who runs the parts department at a chevy dealer. I can buy these heads at cost. I was just wondering if they are worth using on a boat.
They are the heads that come on the crate 502/502
Oval port 110cc combustion chamber 2.25 and 1.88 stainless valves (NOT INCONNEL).
Are they any good?
THEY HAVE TO BE BETTER THEN THE PEANUT PORTS they would replace

So the first (and a must) mod you must make is adding the roller rockers to the tune of about 325.00 bucks.
