If you go that far with a dial indicator, you could add a degree wheel to the balancer, find true TDC, add a pointer, then measure the cam at 0, .006, .020, & .050 lifter rise (at the pushrod tip), and peak lift (average of .050 either side to find true peaks).

Once you have done that, you would have more chance of finding the grind.

Otherwise, run .022, and if it sounds rattly, run them a little tighter in stages.

One of my cams specified .020, I ran it at .014, was slightly rougher idle, but sounded nicer, instead of a "bucket of bolts".
