When one of the online parts vendors was having a "closeout" sale, I bought about six 216 head gaskets, the expensive copper sandwich type, for a ridiculously low price. I'm sure one of them could serve as a pattern guide for programming a CNC machine of some sort. Good idea about stacking the raw material in layers and cutting several at once!
