Are new valve locks necessary

Yeah those my friend are gone. I would send that pic to comp and tell them to step their game up. I wonder if the newer metal is inferior to the old stuff.
I suspect they have subbed the manufacturing out to a jobber maybe even somewhere in China but no matter how much they claim to be induction hardened they clearly are not hard enough to survive , I am running single beehive springs as well so we`re not looking at high lift triple spring pressures here either .
