Now, after your last post: in order to eliminate leaks, you should take the manifolds apart.
You could leave the exhaust manifold on the exhaust pipe, if you do not have to have the joined manifolds planed in order to sit flat against the head.
You are reading my mind today. I was wondering about that very thing. How will I know if the manifolds need planed? Is it something I can "see", or will I not know until I bolt it up and start it?
