I used to do a lot of porting, my 492s got the full treatment, the oval ports on my 427 flowed more than a set of stock square ports with MUCH better velocity and low end, did quite a few circle track heads for another shop here in town, but that was years ago, and they were a lot different animals than the Vortecs. Dennis, my machinist, would be the guy to ask, there are companies that make CNC plots from his port work for some of the import stuff. I just know he's told me several times that almost anything done to the port walls and bowls hurts flow, not help it. Chevy really did their homework on the Vortecs.
