@Moparbrad do you have a photo of the part number on the intake?

Try threading a 3/8 bolt in the end while on the 360 and shoot a pic of the angle from there.
Brad,
here are some pics that might help you verify which manifold (64-5 or 66 up) you have. On the right, the more angled one (as compared to mating surface) is an early manifold. Both early and late have the angled pad, but early is twice the angle as compared to late. The hole size is not conclusive in that all intake bolt holes are over sized for the bolt. Often the 3/8 (later) bolt will physically got into the hole in an early manifold without interference especially on aftermarket aluminum manifolds.

Brad, Thanks for straighten all of that out between the early and late Offenhauser. I am looking for the one you you first mentioned at the start of your post. Joe
