Maybe I am just used to the old Holley fuel pressure regulators, but that appears to be plumbed wrong. On my Holley reg, the higher pressure feed goes to the bottom, where you gauge is plumbed, and the side ports are reduced by the adjusting screw. Seems odd that you couldn`t find headers to work with the factory clutch linkage, as I have seen several stick G body GMs with a 4 speed and headers, but at least you could make those work.
