Exhaust manifold for 318 swap in 63 valiant

FREE BUMP!! I'm sure someone has tried this before but you have to give the thread some time and many folks only come online once a week or so. Be patient and you'll get your answer. Do you have P/S?? Have you considered the early 340 driver's manifold (68/69)?? It's sleeker and a little thinner than the 70 340 driver?? You can see it here in the pics, it's the one that doesn't have the extra ribs.
PS - Also the "early A" section has lots of info about exhaust manifolds if you do a search.
