Um, ALL BBO heads have rectangular ports...
Sounds like a Chevy-centric thing, like their "internal" and "external" balanced flywheels for Oldsmobiles...

Curious how happy you are with the Holley Street Dominator on your 455. I had one on a 403 SB, and while ok, didn't have much low rpm torque. Changed to an Edelbrock Performer dual plane, and really woke the bottom end up. When I built my 455, went with a Performer from the beginning, and wouldn't exactly say low rpm torque is a problem.
