Exhaust Manifold Surfaces
I took off the right side exhaust manifold on my 71 GTO today since it was leaking like a blown gasket. The gasket had no breaks but I did notice an area on the twin ports that was slightly depressed and the gasket looked like it leaked from there. The pictures below show the depression. I don't know if it can be milled out or I need to replace the manifold. I considered putting in headers but the cost is way to high for me to handle right now. Suggestions?
