I have a Snap-On valve adjusting tool V21A, but I cannot wrap my head around what valves it would be adjusting??

SnapOn V21A. Any ideas on what it's used for??
Valve adjustment. Mostly on GM 6 cylinders. The screwdriver tip on the tool was used to adjust the screw on the rocker arm. The 1/2" square is for the socket that you added on the tool, to loosen/tighten the nut.
