2 base gaskets?

[BigBRaptor]

Can I run 2 base gaskets to drop the compression of a 12 to 1 piston to a usable amount for a 390 webcam and and a perfect tune on 93 octane?

I don't think it will drop it enough to run 93

Not a good idea. 1st of all, a tighter quench is actually less susceptible to detonation than a loose setup. It burns the mix better b/c the quench causes turbulence in the chamber enhancing atomization and a therefore a better burn. 2nd, two gaskets is more likely to fail plus they're going to compress an undeterminal amount and last, you still aren't going to get the compression low enough. Run a 50/50 mix and forget about trying to bandaid it.

Or run a 11:1 or a 10:1 piston.
