I don't think Plastigage or Pressurex will tell him what he's looking for.
It sounds like he wants to know the spacing between the component and the
mating surface. That will be dependant on the thermal pad that he's using
and how much it squishes (technical term) down after torque.
Other than a cross section I'm not sure what else would work.

I wonder if you could use the Plastigage that engine builders use to
measure bearing clearances. You put a strip of it in place, assemble
things, then disassemble and the width that the plastigage squishes out
to gives you a measure of the gap.
