Are you trying to use the pink gaskets with stock stamped valve covers? Greg makes different gaskets for specific applications like yours . It sounds like questions about applications weren't asked before the purchase. Superformance sells a gasket that will work for your particular application all you need to do is ask for the gasket for your valvecover and head combination
I use Superformance gaskets on every part of my engine it's dry everywhere :twocents
