Afraid I might hurt myself patting myself on the back for a great job with the intake manifold gasket, but I made the wrong diagnosis....the
oil leak is from the right head gasket. Argggh, so it's back to the drawing board with a new cylinder head gasket. Which one is best for my 427 SO (yep, '65 block) with Edelbrock Aluminium heads? thanx, as I wipe the egg off of my face. steve
