    OK, take a look at this and tell me why it would or would not work to solve splitting the 3&4 exhaust ports. This would solve the cast iron welding dilemma up inside the head.

    The steel tab would be welded to the steel header flange, shaped and filed to fit as closely as possible inside the exhaust port. Maybe even leaving 1/16" to 3/32" clearance all the way around to allow for expansion?

    How many miles have you driven it file fitted? No rattles I suppose?
