Why does'nt someone just build a 12 port cross flow head? there has to be an example available somewhere to copy, right? Take a Wayne head and trick it to the nines, and then digitalize it, and build some. You could get it casted outside of the country if you had to. Heck they do everything else that way now. I can't believe you could'nt sell every one you could build?...
I still am anxious to see the numbers on the 3 port experiment...
