At the KC roundup in September, someone (Jerry Rivers?) demonstrated setting valve lash with a dial indicator. Not a terrible amount of trouble. That would account for the divot.
HRL’s suggestion of properly resurfacing the rockers is probably a better solution.
Before I knew better, I DIY resurfaced mine. I’m sure I didn’t get the radius equal across all, and I am not suggesting others follow my lead.

Edit: I am curious about the “louder when warm” symptom. My valve train gets quieter when warm. However, I have a full pressure 235 and the OP has a 216.
Is this some function of the 216’s oiling system? Pressure is dropping with warmer oil and the oil distributor is sending less to the top end?
