Just thinking outside the box.
If it is a small off-set.
Is it possible?
Could you get a stud, cut it and weld it together but off-set to desired alignment for flange.
The stud would thread in head and the off set would go through flange.
The off set and flange would keep stud
from spinning.
Alternatively could the flange be modified?
I was thinking about taking a die grinder to the flange and just running with the stud as it is set, worst case i'll just get a replacement head and then tig weld the gap I cut into the flange stud hole... its worth a try for temporary measures.. Its ghetto but it might actually work. i'll post with updates
Super cool people, charged me $20.00 to get the stud out.
Good luck
Yeah, I wish the previous owener didnt try to do any repairs before I got to it. The issue for my bike is that he drilled it out... kinda. he drilled 1mm too close to the exhaust port, and you can sort of see a bit of the old stud remaining next to the hole. So right now my options are to try and fill the hole with a tig torch, but i'm worried about welding on 33 years with of dirty and filth on cast aluminum. My next option would be to drill all of that out with a larger 21/64" drill bit, then insert a 5/16" helicoil.. thats the option im really leaning on. The last option is to tap the hole as it, thread in new exhaust stud, and then use a die grinder to remove 1mm from my rear exhaust pipe flange... I would be hoping and praying that I'd be able to get a nut on being that close to the pipe. I'm still trying to decide what i'lll want to do...
The only thing with modifying the flange is it is unique to that location and will be a pain to work with in the future. It becomes easy to forget these things and it will be a nightmare for anyone down the line.

No doubt, a .050 cut on the heads was enough to require grinding on the flanges and trimming the heat shield around the cam cover.
Here’s a jig, but if the previous owner hosed it up, it will be a PITA to align. I’ve seen welded repairs to aluminum heads, a TFS set lifted under boost and notched between cylinders, welded up and good as new.
I have seen that jig and had it been used the problem wouldn't exist. If it is used now however I suspect the hole will be elliptical or eight shaped which will be of no use either.
