which heads ???
 

Im building a warmed over Gen 5, 454 mag, 10:1, fully balanced rotating assembly, scat crank and rods, JE pistons, HP500 cam, roller everything, EMI thunder. Stock rev limit is 5150, but thinking 5200-5500 might be possible.

Im down to needing heads. I have a line on a set of 088 take offs with 26 hours, but not sure if thats the best that I should have.

What is everyones thoughts ?

if it is in the budget i think some afr 290 oval port aluminum heads would work good for that application,call bob madera and see what he suggests.

Phuck it,some people just don't listen!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!

I was actually thinking of factory GM heads. my pistons are domed

anyone ????

I never get fast answers here. Post it in general boating discussion - more people seem to read that!

thanks.

Gen V's are different then the Mark IV's especially when it comes to heads.

so what are my options for OEM GM heads for my gen 5 ? will gen 6 heads work ?

I got brand new gm 188 for my new motor bc one thing goes wrong you will destroy motor.. Did that once, I can only get 5150 Rpms out of the motor, but no porting done.. I hear the power is in the heads... So if you have the money the afr prob will make u happy
