I to have bolts holding the exhaust manifold to the head, or one bolt and
one stud and nut. The stud and nut came off ok, the bolt is not budging
after  much coaxing, pb blaster, heat, and impact wrenches. Does anyone have
any suggestions. I have already broken one. Trying not to repeat. This sort
of fits this thread, any one have any ideas?
