Mushroom Tappet Pitting

The right side mushroom tappet adjuster is pitting, all others are ok. 2000 miles on tappets, Kibblewhite valves.
I read to install stock adjusters on the exhaust, better angle. Maybe just a bad adjuster, hardening is bad.

Mark,
Mick Hemmings claimed that the right side exhaust is a common problem of not being centered over the valve stem and that he commonly fits two or more shims to that rocker spindle to get it central.

Is that the kind of pitting they call "spalling"?
