66 Dart GT HT Whatsitgonnabe?

I guess the head could be warped a little bit on the face where the manifold bolts to the head. I had the machine shop check gasket area where the manifolds bolt to the head on a slant head and it was not flat! A pass or two with the mill took care of that!

I haven't had time to find out why it's leaking even worse but I have a feeling it's interference btw block and manifold.
