How much money you looking to spend?
Quite a few ways you could go but that all depends on your goals here.
The safest bet, get brand new heads, but that obviously isnt an option for everyone.
Frugal approach? Assuming you are not looking to have any other work done on the heads, and assuming the insert is the solid style and not a heli-coil, screw a stud and test fit your heat exchangers on the bench. If the stud is still angled well enough to let the heat exchangers slide on properly then I would say that may be the best you could hope for with that head.
If you have the proper setup to do so you could attempt to re-drill it straighter and run an oversized insert, but that could be a gamble as well, especially if the current insert is actually functional as is.
Personal opinion here, but anything beyond that requiring welding on the head I would just get new (as in brand new) heads. Exhaust stud issues may be my least favorite thing to deal with on 914s
