Source for 273 Head Gaskets??

Slatsixdan had a source for lots of obsolete parts...Northern Auto Parts? Aisles of lots bought out from old stealerships and tons of NOS parts still in rotting boxes. Could you get .020 shim stock and actually make a head gasket? Cut the bores to size, punch all the passages out with a knockout punch and use a wire and mallet on a piece of wood to emboss all the raised portions to set the sealing crush height? Ive seen them come off old blocks and pitched them (351C bathtub gaskets, B-RB too) but I bet you could lather them up with indian head shellac and reuse them? I dont remember if they had a seperate fire ring or not, im thinking no.
