I'm no expert, but when I went with .040" gaskets, my machinist said that it was fairly extreme and said he wouldn't recommend any thinner. Keep in mind that the piston actually comes up out of the bore by a few thousandths (like .007" or something), so you're going to have less than .030" clearance between the heads and the pistons.

but its a stock ls1 block i only changed the rod bolts, i used to have diamond piston before but that motor is cracked with N2O.
