Snowman, this is not the first time I have seen you make this suggestion but it is dead wrong.

If you only heat the stud and not the case you are only going to make the stud expand in the bore and tighten.

One of the secrets of stud removal is cooling the stud when the hole is at its maximum temperature to break any bonding between the two and to give you maximum clearance which will also reduce damage to the threads.
