MLS cometic head gaskets in a magnum with a high lift cam

Hey guys
Has anyone used the MLS cometic magnum head gaskets on a magnum engine with a high lift cam.
I want to replace them but I'm currently got LA style ones. The LA style ones don't have gasket around the pushrods where the magnum ones do. I seem to remember having to trim the magnum gaskets around the pushrods in the past but not 100% sure. My cams lift is around .600
cheers
