Default GT40P Heads 59cc?
Are GT40P heads 59cc heads or are they something else, also what are the stock heads 61cc?

I think the P heads are higher...like 64-65cc's.... All I remember is the stock compression goes down a little w/ them.

My bad...I got them flip-flopped!! The P heads are 59cc, the 3 bar GT-40's are bigger.
