Thank you for your reply Pat.My question is what c/r should I shoot for and maybe which pistons I should buy??.

Given a piston choice,which RHS cast head should I get??.180cc or 200cc-64cc or 72cc??.

I would be interested in hearing more about a cam that is a little better.A shelf built or maybe you could PM me with one of your custom builds and costs.

Again,Thank You.
