.13mm = .005" So you have pistons sticking up .005 out of the deck. If you want the piston to deck clearance to be .024, that leaves you only .029" for the headgasket. So you need a super thin gasket, not a thicker one. A 1mm gasket is .040, so that would give you .045" clearance. If you look you might find a thread about HKS 2mm gaskets where the idea of peeling off layers was talked about. I had been under the impression that all of the layers were the same thickness but apparently they are not. I can't recall how thin the thin ones were, but I seem to think that there were 5 layers, so they'd have to be thinner than .040".
