Aftermarket types vary in all sorts of ways. Some were made billet style so they had to be two pieces bolted together. Ford's design was more for coolant flow velocity than for capacity. The 8BA design was the culmination of all of there flow control tactics with the longer/larger ports at the rear and smaller ones at the front so that it would force more flow towards the rear of the block, then after passing into the head it had to all come forward to the front mounted outlets to the radiator.
Barney Navarro had an interesting explanation of how some race engines were set up with a small collector soldered to copper tubes that was inserted into the block to funnel some of the water pump flow at the front and force it to go to the back and middle of the block on the engines built prior to the 8BA era. The 8BA design sort of eliminated the need for that.
Its more about the velocity of the flow and how much gets to what location than it is about volume of flow.
