Lifter failure

Anyone have any insight on what years the lifters started going to hell? I have several older NOS cam and lifter packages, and thinking they would be alright. From the 90's I would guess by the old boxes.
I'm pretty sure you're OK with '90s stuff.
Is any of it for sale?
I'm not turning this into a sale thread Mike, I swear! :p

What year did the first Mopar Direct Connection program change the name to Mopar Performance?
I *think* the first Mopar Performance catalog was in 1989. Direct Connection ran well into the '80s for sure.
