But don't regrind them too short or you'll get a rattle you won't believe as they bottom-out.

Well, no one mentioned replacing. I guess price might be the reason.   https://shop.srmclassicbikes.com/product/a10-cam-follower-set-stellite-hard-faced-set-4

Those don't look bad, a very slight grind should do and the stellite is quite thick.
