I did a pattern once by taping a piece of poster board on the block, tapping around the exhaust ports and bolt holes with a brass hammer to embed a pattern, and cutting it out with an Xacto knife.

Same way I have done it, thin cardboard, like a cereal box and light taps with a ball of a ball pien hammer, it will actually cut the carboard into a gasket if you go over it enough, gaskets sometimes aren't always exact (Chevy guys know as there where so many port variations) might have to screw it down through two bolt holes to keep it from moving.
