Someone had told me once that you can drill out the heads and use a stud one size bigger and it would solve the stud breakage problems for good, the important thing is that if your breaking studs don't just replace them and think you fixed the problem, the reason the studs break is because the exhaust manifolds warp, so before reinstalling the manifolds make sure to check the gasket side to see if they're flat, if not you could either replace them or see if a machine shop could shave them down slightly to give a flat surface
