The Pro-Filer head is the same core boxes as the Z304. Pro-Filer cast them. We took that head and did our own thing. Darin designed the chamber before he went back to RM. The intake is a hand port I put into that casting and then was put into the core boxes.

It flows well, makes good power, just hasn't caught on.
