Man, these deep dish pistons and 70cc heads are killin my comp ratio. I’d like to get it up to 9:1+ being I’m gonna run e85.
Is it ok to mill the heads down to 58cc from their current 70cc? (sb sidewinders) What is the minimum piston to head clearance I should run turning 6200rpm max? Steel rod/forged piston combo? Do we really need to align hone when installing main studs or is it a money making scam?

Higher compression ratio options when starting with 7.5:1?
