Use the proper Snap On tool with the unbroken ones, impact wrench is good. Heat with a propane torch, get it very hot all around the stud boss and then use vice grips on the broken ones. I ground some flats on a couple of them when I did my 2 cases, a few were difficult but they will come out. The flats are so the vice grips fit better.
Don't be afraid to turn them in and then out. That seems to loosen the grip on the stubborn ones....along with heat and force of course.
