Seems odd that the heater wouldn't loosen the nut, leaving the stud in the manifold. When it didn't turn with moderate force, did you heat cycle it 3-4 times more ? With a stud like that, I never use a power tool until I can get it to move by hand with a ratchet. I'm not as good as you with drilling out broken fasteners and will test my patience level with attempting to remove without breakage.
