I haven't talked to him for quite a while, but there's a guy here in the Minneapolis area running a set of the reproduction aluminum manifolds on his '63 Catalina. They were coated with Jet-Hot or one of the other similar products, and seemed to be holding up to street use. Of course, those kinds of coatings weren't available back when your dad was trying them.
