Heat may help. From my experience the ones that had given me trouble had galled on the shoulder section of the stud with the aluminum block. A little bit of aluminum had came stuck on them when they were out at that area.

I think I left one or two real stubborn ones being afraid to break them off.

Having a few of the studs in the engine helped align the new manifolds when I installed them. Is there a reason you're taking them all out?
Speaking for myself not the OP, I had bought new replacement ones and it is good to replace them once you are there, for next time they will be in better shape. They rust and corrode with additional heat there. By the way some of them had come off as the nut had gotten corrosion welded to the stud. So you need to have replacements in hand. There is risk of breaking them off though.

About alignment, you put the new replacements ones in after removing old ones, so they still would do that alignment job.
