cast iron W2 intake?

MANY heavily ported W2s have rectangular ports. I've seen a bunch of W2s with rectagular ports, whether it be drag racers or roundy-round guys. I have a set of Batten heads with massive rectagular ports that I got from a dirt track guy. Bob Glidden's heads from the 70s pro stock cars were rectangular, Dennis Maurer's ported W2s are rectangular.

And yes, a W5 has the same bolt pattern, but with rectangular ports, so it could be used on both. Of course, this intake wouldn't be something to bolt to a set of as-cast W2s.
