My heads are 'studs' too, high riser studs at that.
Seriously, I can remove my heads but I DO have to take off a motor mount and jack up the engine for one side. I'm not crazy about the idea of removing the studs from the block myself. One side or both? As for me, I would do only the side that has a problem.
Whew, you do have some bad luck with motors Brent, I feel bad for you man.
