The overall area is probably close, but the Victor has a built in roof for each runner that extends into the opening which keeps the runner heights very similiar, port to port. The POS has differing heights on the entry to each port, and that in effect changes the runner lengths. Airflow likes parallel ports, with slight taper for speed to increase. Anytime you increase the port height, you move the roof away from the floor, which lengthens the port in theory, but it shortens the parallelism, and shortens the ram effect as well as velocity. Will work better with more cubic inches, or shorter rod ratios. The most powerful engines today like ports that accelerate the air all the way to the valve, and that means as straight a path as possible the last couple of inches. I know swirl is important, but cylinder fill, or superfilling nets more power on a drag style engine. Joe-JDC.
