Thanks for the welcome. I am trying to track down a new cylinder head. My local machine shop told me about a block off kit that is/was available to delete the jet valve, so hopefully if I am unable to find a 2 valve head, I ca still find that kit. I'm on the fence about the AC. It would be great to have, but maybe something that I work on down the road. IMG_35511.jpg20200216_125730.jpg
