OK, I got my engine removed and cleaned and up on the bench. After replacing the leaky rear main seal I decided to bolt on the AA motor mounts to see how the fit. The right side went fine however close to the exhaust manifold. I noticed as I started to tighten up the left side that the mount was hitting the manifold and would not allow it to tighten up. My question is if I keep these manifold which I am not crazy about, should I grind an area on the manifold to give clearance? Grind an area on the mount? Would this compromise strength of the mount? Also, both manifolds are rear dump but one goes off at an angle and the other straight down. What are some other options or opinions? What about headers? I'm kind of open at this point and in no real big hurry. Also the pictures will show what I'm talking about.
