Head Gasket for 3.908 bore
Just trying to find out what head gasket size are people using on a 3.908 bore on a Ls1. Is a 3.910 cometic gasket cutting it a bit to close or ok.

3.910 is perfect, it is .0020 over 3.908
Plus if the bore is 3.908 right now, then the piston is @ 3.904 (assuming an NA build), which means you will be fine!!
And since you know the piston is .010 out of the hole I would get a .045-.050 thickness gasket and have an optimal quench of .035-.040
Goodluck
