Yea, I'm measuring +.010 "
If you're there, then a standard Felpro kit gasket (PN 8553PT) will work out and give a piston to head clearance of .040" + or - a bit. Nice for a quench gap. Just be sure that you are at .010" on ALL cylinders. (With a
nominal deck height, those pistons ought to stick up around .018" above deck.) I personally would check how much that changes with piston rock at the upper and lower edges those forged pistons typically have some pretty loose clearances and will rock more than cast or hypers.
Your static CR computes up around 9.8-9.9 with the 65 cc SM chambers, that head gasket, and the 2316's out of the deck by .010". That's a tad more than the actual production 340 SCR, and may end up being a pretty nice spot to be in IMHO, depending on what you plan to use the engine for.
