They are a very economical performance upgrade designed for use with other performance enhancers and are machined to accept S&S compression releases. 79cc heads 1.940" intake and 1.575" exhaust valves.
For street performance use they are ideal. With 583-585 S&S cams not necessary to machine/grind valve reliefs on pistons. That alone should be enough incentive to use these heads. The added compression ratio is good for a few ponies.
