That's weird. Because the left side was very losse on the header pipe, but the nut was not in all the way to the head. But still stuck. The right side was tightened all the way up to the head. Wonder if the PO had a similar experience with that.

I read something somewhere about the nuts having various tolerances.
I found when replacing mine with unused OEM nuts. One nut was too tight in left head but perfect in the other. The other nut was too loose in the right head but fit perfect in the other???
You might try a few different nuts and see if you czn find the perfect match.
