The problem with both the GE-60 and the old S grind is the lobe centers.
Motronic cars have 113 lobe center cams which cut the lift at overlap down. The ge-60 has a 102 L/C and the S cam has a 97 L/C. Both cams have a lot more lift at overlap which decreases the valve to piston clearance.
The 964 grind or the 20/21 grind are the most popular for use with stock pistons.
