Yep, I was in that group. Decided I wouldn't live long enough to enjoy them. If Edelbrock, Speedmaster, and others who make heads wanted to greatly increase their sales, they would provide round port exhaust manifolds. Larger company like this could get manifolds in the market in 6 months, start to finish. It takes some clout and $$$ up front to get a foundry interested in limited run stuff. But they will do it. Look at what Tom and his associates pulled off with the bathtub intake replica. Much more complex casting than an exhaust manifold. Iron replacement manifolds are available for almost any American engine you can imagine. Although the Pontiac manifolds are much better than most, they are not castings for the next space shuttle. As iron castings go, can they really be compared to an engine block or cylinder head? Foundries all over the country are pouring them every day.
