302 head exhaust port bulge and a '65 Valiant LH manifold

I don't know exactly how thick the manifold is at the point of contact. Maybe taking a little off of each could work?
I do like Professor Fate's idea if I had no other manifolds here to use.
I have a rear dump 318-360 manifold that will work but requires that Borgeson coupler. I was trying to save this guy the $175 though.
