zealworks comp calculator lists a y8/z6 headgasket and a y8 2 layer. i picked up what i thought was the thinnest aka 2 layer headgasket from a guy genuin honda unopened part but uppon further inspection of it. it has 3 layers. so its not the 2 layer i desire from the zealworks comp calculator. does anyone know the part number for the 2 layer head gasket?
D series fyi

 

Just take the pins out and remove the center layer if that is what you're after. The .15 compression points you gain on the Y8 aren't going to be noticeable...hell on any motor for that matter.
