While the front end was out of the car I dealt with a spacing problem. the castle nut on the idler arm had cut a groove in one of the header tubes. Pulled the header and welded in a half-pipe to gain clearance. Even though the header hadn't broken through, with the repair the exhaust is noticeably quieter.
