Well... good news is that one header is out... bad news is that every single stud gave me a fight. At the end, all but one of the studs came one and it did as a single piece with the nut!
They did not break flush, so that is a good thing... some heat with a torch, more PB, and an extractor and I hope they come out... if not I am going to put Christian's tool to good use.
