Hopefully, this helps. I had a broken stud that was the last stud all the way to the right on my SR head. It broken literally flush with the head. THe way I did it was drench the bolt with PB Blaster 5 different times over night, literally drenched it.
Drilled the middle of the stud with a craftsman cobalt bit about 1/3 the size of he hole, which cobalt is like toughened steel. Drills through bolts like butter. Very expensive too. I used cobalt bits to do safety motorcycling stuff to prep for races. Then used the square easy outs by craftmans, knocked it in with a hammer and it cam out, not even touching the threads on the head.
The drilling is the most important part. Just take your time and it is fine.
