Cometic is nice for fine tuning thickness...
if you are not worried about changing compression based on piston/HG/etc. just go OEM. there are 600+ cars running OEM HGs.
FYI 96+ y8 HG is the same HG as the 92-95 z6, except half the price(diff part #, but same gasket) :TU:
im going to be running an OEM z6 HG(didnt know about the y8 deal until after i bought it), its already coppersprayed and the head is torqued down
