273 Head Gaskets

I sent an inquiry to a gasket maker "Olsons Gaskets" about an embossed metal head gasket OEM style. How many would be interested in a group buy? These would be a round 3.815 bore or possible a copy of Toolmanmikes example if they have the tooling to stamp an irregular bore. Im trying to get a quote on 20 sets.
Depending on price I would buy a few sets to have and sell. The pressing and trimming dies would cost a fortune. I think a round bore would be just fine.
