Boared .90 over good idea?

Yep, big bores only go 3 sizes up. Then you have to replace the sleeve

i think the big bore can only be bored out a few times...correct me if i am wrong

It can be bored out but then after its done, it will need to be re-sleeved.

Vito's sells pistons up to .020 over. That's two bores if your lucky.
