guessing there will be gains in compression by using thin gasket. anyone elaborate on this for me?
In theory, you could take off as much as you wanted until the valves started hitting the heads. The thinner the better, generally you'd want under .040" for decent squish clearance/velocity. So .040" head gasket, assuming zero piston/block deck clearance.

Shorter PTO usually. Not sure about the rest.
