I now have some pictures of how I removed the steel plugs from the Offenhauser 2x1 and 3x1 intake manifolds for 216, 235 and 261 intakes. I don't know how to post pictures here on the forum, but I would be glad to send the pictures to anybody who request them. I also still have some free aluminum slugs that can be welded in to stop any leaking for those who run their intakes with hot water heat and wish to weld them in.
