I figured that I would let you all know that I took the risk of trying to straighten the stud enough to function by using the simplest method...a hammer.
After reading the comments above, I sort of expected to break the stud and I didn't want to break it off at the manifold. So, I put a couple of washers on it, then cranked down a couple of nuts pretty firmly hoping that if I did break the stud, there would be enough of it left sticking out of the manifold to facilitate removing the rest without having to drill it out.
I put a couple of nuts on the stud above the apparent center of the bend and gave it some modest impacts with a hammer. Taking it a little at a time, it was eventually straight enough to get the header pipe flange on without issue.
Now I have to ask another basic question...
In the attached photo, does the gasket on the right get used in my application? If so, where? I would assume that the donut-type gasket goes between the manifold and the header flange. Part of me guesses that the flat gasket is for a different application...but I have been very wrong many times!
