Art's son is Michael Francis. I spoke with him about a year ago when I was starting to make valve covers. He asked me why I was doing valve covers that were similar to his, and I told him because nobody could get his covers LOL. Same with his FE heads, FE intakes, etc. He said he is working on getting that pipeline filled, but that it would probably be a 3 year effort. I think they do a lot more business in small block and 429-460 parts, so that probably gets most of their attention.
