I've never really heard complaints of round ports in 67's and as a matter of fact see a few at local gatherings.

If it's truly a problem it would be easier, less work and probably cheaper if you just swapped to an Eddy or Kauffman Dport head and left the rest of the engine alone. Figuring out what cam is in it wouldn't be that hard and if you're dealing with a 455 I wouldn't want to go too tiny on a cam anyway, like that 2801 for instance.

All that work and money spending sounds a bit excessive over a round ports exhaust dilemma.
