which head gasket?

my motor is at the machine shop and they just called me to ask which head gasket i want to run. they are suggesting a gasket that is .060 compared to the one that was on there at .040. i wasn't hitting at all but with the pistons out .010, they want to play it safe.

what do you guys think? we are trying to stay in the .035-.045 quench factor, but the original had me at .030 and the others will take me to .050.
