I have used this method hundred of times & works perfect. The block & threads see way less heat than the method so many try of heating block & studs to attempt to get studs out.
There are many reasons studs & bolts break to include:- bottoming out, galling up, over torquing, or like is common with flathead corrosion from water jacket end of studs along with many other reasons. All of these reasons for breaking can require different methods of removal.
