I know of the non performance heads that are out there for FE's. Ford also made a low riser performance head and the famous medium riser head. What was the high riser head about if such a thing existed? The tunnel port head and the SOHC head has been talked about at lenth but there is no info I can find on the high riser out there. If it existed it must have been a bummer, or is it really the tunnel port head ? Just curious.
