    Well to save you some brain cells trying to figure out a head design, if you stay with those pistons you will need a 23 head. Because they are a hypereutectic piston that will limit, somewhat, what you can do as far as performance. That is a pretty heavy piston and pin combo. I don't think you will need to spring your heads for anywhere near .800" either.

    I suggest you decide how much HP and what kind of rpm range you would like to shoot for and that will help people give you a better answer to your questions.
