Thanks!

Blair,
The propane blow torch does not produce too much heat to overheat the aluminum crankcase. Use Mapp gas for more heat application. Concentrate the heat to the area around hole on the crankcase for each cylinder head stud. The goal is to melt the thread lock adhesive to loosen the stud/s. Snap-on stud remover combined with an pneumatic impact wrench does the work for me and I seldom use heat. Start with a medium setting for the impact wrench then go to high torque as needed. I average about 4~5 mins. a stud compared to 1 hour per stud 20 years ago using vise grips.
