Try Cometic gasket. They list a solid copper one for the 100. You can also
order it an any thickness you need if you want change the CR. The solid
copper gasket requires flat mating surfaces of 50RA or smoother. The
instructions also require you to coat both sides with a gasket sealer such
as Gasgacinch or something comparable, but just normal torque specifications
are called for.
