I've thought about brazing, but didn't what other problems it might cause particularly for coating, paint, plating, ceramic. What about building up around the weld on the inside of the flange? IIRC there isn't any way I'm going to get a good seal with the new headers and the gasket. I'd also like to match the port a little closer from head to headers IIRC I couldn't.
