head gaskets and compression

A few week ago, we were discussing the effects of using multiple, thin head gaskets on compression. I turns out that (according to the Puch manual), the high-torque cylinder for the Maxi Sport 1.5 hp engine requires a thicker (~1.5mm) head gasket rather than the thin, more flexible type (four of which were installed when I received the bike). I happen to have a bunch of gaskets of each type, so I installed the correct (thicker) gasket, replaced the head using a torque wrench and measured the compression at 115psi. Will I cause any damage if I replace this with a single thin gasket in an effort to boost the compression? Will I see much of a boost?

Thanks,

Dave
