Re: How hard are Gibson Headers to install?
The engine side, which is the head, should be OK. The problem is that once a manifold heats up it warps when it's taken off. The runners torque from the heat. They don't stay true and sometimes it's almost impossible to reattach them. Even if you can fit up the manifold there's now guarantee that the runners will seal against the head, hence the facing. Some people use two gaskets to help make up the difference in between the manifold and the head, but that's masking the problem.
