broken exhaust stud removal

twistthethro said

not sure if it's ok to do on a head but a great way to get a broken stud out is to heat it with s torch and touch beeswax to it. The heat will instantly suck the beeswax into the threads and the stud will come right out

I'm sure if you use a propane torch it wouldn't overheat the head. Heads get up to 350/400 degrees normally (in certain areas). I have heard that beezwax does work well for removing stubborn bolts, lots of u-tube videos!! But if the OP has the stud broken off "flush" he'll have to use an easy out once the wax gets in there.
