im just as curious as the next guy..... I am really going this route because the smaller combustion chambers will bring my compression up on my little 383 and provide a great quench situation on the new engine i am building. that and they are advertised to flow incredibly well. We will see! I can't wait to get these into Jim's hands and get some real world #'s. I am also very interested to see what Jim has to say about the valve guides, valve job and the over all assembly quality.
