Is there a head gasket made by Felpro that will work with these heads,any cooper gaskets?The recomended head gasket by GMPP is $60.00+ each.What are you guys with these heads using?Thanks.

For a 454 a 1027 will work, for a 4.5" bore a 1047 will work. Fel Pro numbers. About $35-40 each.

By the way, those are basiclaly just Edelbrock heads so you can use Edels suggested parts. Good luck.
