A friend of mine uses this tool to make headers for the Buick 215. They also have a rectangular port and the tool works well. The Buick has only one size port, it is a lot of effort to make two tools. He makes a 2" long piece to which you can weld on your own primaries. If someone did something like this for the 235/261, they could be used for any configuration of header. I just came back from the machine shop and we are making a set of dies so that you can use flanges such as those made by Hells Gate Hot Rods.
