My exhaust was leaking at the 2 inner ports
...pic... ...pic... I took it to him and he put a straight edge on the manifold.
you could see where the outer edges were hitting first.
he endeded up milling it and I believe he took off less than .020 before it trued
this is what it looked like when he finished.
...pic... nothing had to be taked off the intake.
If your worried about your alignment rings you can take those down with a file.
I had to call three shops before I found someone willing to mess with it.
