From what I can remember there were 2 heads designed. Darin designed 1 of them and for some reason the other head was the one used.JohnsnsFord2@aol.com wrote: ↑Wed Feb 12, 2020 1:20 amStan Weiss wrote: ↑Tue Feb 11, 2020 2:21 pm I have no idea what todayes heads flow.

The head didn't determine the flow, there was enough stock to cut about any shape you wanted into it.Stan Weiss wrote: ↑Thu Feb 13, 2020 11:12 amFrom what I can remember there were 2 heads designed.
