It would appear from azzkikr's pics that the TF head would also have the ports shifted slightly to one end since all the ports line up when the gaskets are centered on the bolt holes when the numbers are facing out, and don't line up when you flip the gasket over. Seems like perhaps that's what TF used to determine the port layout/bolt hole relationship?
