6.0 block, 5.7 heads, what head gasket?

The heads are o-ringed, so it looks like I need to go with graphite.
Is there a graphite 6.0 gasket?
Is it a bad thing to run a 5.7 graphite on a 6.0 size cylinder? I would have a little fraction of the graphite in the chamber, right? But maybe that's ok, as long as the piston doesn't touch it.
Do I have choices of different gasket thickness with graphite, if I want to tweak my compression ratio? Or does the graphite only come in one thickness?
(thinking about a 402 with my TEA 5.7 heads and my STS kit)

ttt, need to know something on this.
Looks like the 6.0 cylinder is a 4.0 bore, compared to the 3.898/3.905 on the 5.7. I measured a set of graphite 5.7 gaskets last night, and they are just a little smaller than 4.0, so part of the metal sealing ring will be in the combustion chamber.

In the following thread, TwnTrboCE is running 5.7 o-ringed heads on an LS2 using an MLS gasket... So maybe I can run MLS gaskets with my o-ringed heads after all.
