Broken Ex Manifold Studs

I believe Scott Justusson (sp?) posted this trick a long while ago.  If
you, or someone you know, has access to a MIG welder use it to build up
the end of the broken stud a little bit at the time so that it protrudes
beyond the surface of the head.  At this point you could also just tack
on a nut to wrench with.  The heat from the welding has the benefit of
tending to break free the stud.
