Insufficient Hardness of New Lifters & Cams

[Shoebox]

Talking with my machinist while dropping off a block recently, and he mentioned issues he's had with some NEW cams and lifters having insufficient Rockwell hardness, said it seemed to begin 3-4 years ago. I've read here on the Barn about adjustable lifters from some sources being "soft" and a couple years ago one our own cam gurus here recommended I not get a cam on a new billet due to inconsistent heat treating.


Wondering what you guys have experienced, opinions, etc?


I'm not about to buy a cam right now, but would one be hesitant to purchase new, safer with reground on good core? Appreciate any input.


HAPPY NEW YEAR!
