318 horsepower

thanks rumble...

as for the -302 heads. they work FINE! just stick a set of 360 valves into them. i only ported the exhaust side on mine! i didn't want to mess with the velocity on the intake side, so i just cleaned up the casting imperfections.

IF you already have them use them. i have never messed with magnum heads, but if you don't have -302s, might as well buy magnums. downside for magnums is the rocker assembly, but for a mostly street car NOT an issue.
