273 Exhaust manifold

Yes the steel shim shield is what was used, there was no "gasket" though, context means everything...
So, is a steel shim head gasket "not-a-gasket" too? 'Cause my 66 273 Commando also had a steel shim that was embossed, much like the heat shield not-a-gasket, between the head and block when i took it apart.....for context.... .
