I keep having a problem with my intake gasket on the rear of my 351 Windsor block leaking. It only leaks with the weber manifold. if I put the Edelbrock RPM back on its fine. I have tried the cork gasket with no luck. I tried black Loctite RTV and it's leaking too. This is going to get expensive if I have to keep buying intake gaskets.

Any other ideas?
