With only 9.8-1 compression the GE 80 cams will be awful down low. It would come on the cam around 5000 or 5200 with the 46mm Pmo carbs. I would stick with the 40mm Pmo's and a GE60 style grind.
I like cams with wider lobe center when using Pmo carbs. Something like 104 , add some lift and about the same duration as the GE60.
The GE60 has 102 l/c and the GE80 has 100 l/c.

The webcam 120/104 is similar to the GE60 cam.

Also, 78 SC cams can only be made into GE60 or GE80 cams by welding. I prefer to make them on new castings.
