If you are going forced induction, you'll want to go with the 64cc heads... And maybe even a small dish on the pistons. If you're going all out you'd be better off shooting for like 8.5:1. If you go heads/cam and stay naturally aspirated, you could actually get away with more compression depending on your cam profile.
