How high can I up the compression with a 2v? Mod max sells flat top pistons and according to them that will bring it up to 12:1.

on 42cc PI heads you can go even 12.5-12.85:1. Have fun using race gas for 330rwhp, though.

if you knock the swirl dam out of the head you will have a 11.1 compression ratio and be able to run pump gas

That'd be perfect for an E85 combo. Much cheaper than premium and 105 octane.
