Spyder, You're definately on the right track. Your best bet would be to find an old pair of Boss351 heads. Big ports, closed combustion chambers, and ready for screw in studs for the adjustable rockers. But think about this: you only really need 4V heads if you are going to be making horse power in the high RPM ranges. There is no middle of the road with Clevelands!
