I spoke to the head of production at Detroit Gasket (the company that supplies Chevrolet with these gaskets) a few years ago about the steel shim gasket situation, and he said their dies are just too worn out to reliably produce good stampings for the 633 pn. He was willing to make another run if someone would belly up for 1000 gaskets and be willing to pay for culls. He said GM told him that the last batch he produced in 1999 would be the end for them because of low demand.
