I'd like to know. My sons 89 5.0 has 256k miles on it now, and the engine has never been cracked open. Runs like a swiss watch, and the darn thing still went 13.85 at 100 mph at the last track outing. If he decides to stick a cam in it, I'll probably just reuse the lifters, lol.

I have a brand new 502 GM crate sitting here with a factory roller cam, and I plan to just use the lifters in it when I do the cam upgrade.

But none of that means I'm afraid to use what's available out there.
