There's a trick that I read about on the web for removing broken steel studs
from aluminum engine heads where you find a washer with the same interior
diameter as the stud, use a TIG welder to weld the washer to the stud, then
weld a nut to the washer. Use an impact wrench at the lowest setting to
turn the stud out.

I had a real tough plug to pull once. I JB welded the allen wrench into

250f
measured with my trusty IR temp gage.........

This was my next suggestion.
