I just put a whole exhaust from an 80 DOHC on to my 72 SOHC in a 76 frame

I made sure I got the clamps and half circle shim thingies. It's the same hardware I think used on your motor to mount the original header. New copper gaskets are a must. The port spacing is the same between the two engines

Sweet, I'm going to tie this pipe in
But it will be mounted parallel with the frame(chain stay)
