Just tried Chris' method on one of the studs-it worked like a charm with my not-so-expensive stud puller. It's one of the ones that looks like a sparkplug socket and has three "fingers" that grip the stud. I'll pull the rest tomorrow.

I actually focused the flame on the stud about 1/2" from where it enters the case, then gave it a test turn which didn't require much torque at all. I'll tell you what, it also avoids the squeamish feeling I'm sure I'd get if I was heating the case directly.
