Default increasing compression ratio

4.00 bore
3.48 stroke
12cc dished piston
.25 below deck
.018 compressed steel shim gasket 67cc
67cc head chamber
=9.16:1

Can I use a different gasket to increase the comp. ratio?

I doubt you'll find a thinner head gasket...you could mill the heads, though.

zero deck those slugs...compression will get interesting with 67cc heads and a gasket that thin

Assuming you meant .025" in the hole, you don't have much, if any room to reduce quench below that very desirable .043" you're at now. Simplest method to increase your CR would be milling your heads.
