Its a 4.5 v8, 90 cadillac deville. First off, I pulled the head, so I think I should replace 10 bolts. 5 inside the head itself, and 5 that are on the outside that go through the exhaust manifold and the head, iirc. Then on the exhaust manifold, there are bolts that hold the exhaust manifold to the head itself. I broke two of the bolts that hold the exhaust manifold to the head, and 2 of the bolts that go through the exhaust manifold AND the head were already broken, which was what was causing the head gasket to leak in the first place.
