i know copper exhaust gaskets work great but i believe a copper as a headgasket would be too soft of a metal to work for high boost applications... don't quote me on that though

They use them on TopFuel Dragsters running +30bar of boost. but those ones have steel rings cut into the block so that it all matches up well. I'm not sure about lower cost ones though.
