I've got a few broken studs and my manifold-to-head gaskets are shot. I'm planning on removing the manifolds and installing all new studs. I loosened one pretty easily with the engine slightly warm. The stud just screwed out of the head. Any tricks to putting them back in? Any of them go into water jackets? What do I torque them to? Do I use anti-seize? I'm going to use Ford studs and they look copper colored. Anybody have a source for manifold to pipe gaskets and EGR tube? Thanks.
