Cometic has a gasket that is very thin I believe around .021..
Check to see what bore dia they offer in that gasket. Frankly Id rather run a Cometic than a steel shim...All else equal.

The cometic if I remember right is .027
John is correct. This will still yield decent quench for me (put me at .047) but I'd prefer to be spot on at .040 and 10.5:1 compression. Also, I'm not sure my deck/head surface is ideal for a cometic, I understand they're fussy about it.
