My '65 exhaust manifold is a 2 bolt deal as well. I wonder if my pipe was flared out too much, my donut is not nearly as visible. I'll ponder your pics and look at mine again. Or maybe Homer has been chewing on my donut. I've got a spare pre-'65 exhaust manifold with 3 bolts. I picked it up to replace my bad exhaust manifold, but ended up using the 2 bolt one. Think I'll store it.
