Yes, i already viewed the sticky about head gasket thickness selection, but i have a few more questions.

I had my bock deck machined, approximately .003" was taken off

I had my head machined for a second time, totalling in about .006" taken off.

This leaves me with .009" (.2286mm) total taken off. Stock head gasket thickness is 1.37mm, so my target head gasket thickness is around 1.5986mm.

Also, my bore size is approximately 3.3085" (84.0359mm). Does this mean i can use an 84MM bore size gasket? Or with an 84mm bore gasket will the .0359mm cause issues (piston hitting gasket)?

These are the two closest gaskets i can find available for what i need.

I figure its better to go with slightly thicker than needed rather than slightly thinner, is that right? I am more worried about bore size problems, should i get the larger 86mm bore size to be safe, or will that mess with my compression? Thanks for the help.

I would ask that company for the part number of the gasket that is shown in the two links you provided. The picture is of a 2jz gasket, not a 7m gasket. You want to be sure you get the correct gasket.

Greddy makes a 1.6mm gasket and I have 1.6mm gaskets also.
