If you are interested in the cylinder head package, now is the time. I will be contacting the people on my list in the next week, and then finalizing the number of the head packages that I will be building and ordering the tooling for the castings. If you are not on the list but want to get one of the packages, you can leave a message on this thread, email me at jayb@fepower.net, or give me a call at 952-428-9035. Thanks, Jay
