I'm gonna see what happens today when I set it on the engine first. The front side is easy. Little silicon boom. The rear just looks like a terrible design. But we will see what happens.
The exact reason I didn't use the Magnum gasket, and since I have NEVER had a problem using LA gaskets and end seals I stayed with them on the Magnum. (Just trimmed the edges of the rear one to fit the smaller groove of the Magnum.)
I used the black felt type rail gaskets with sealer and the OE style front and rear rubbers.
