Hydraulic lifters - are these good?

Thanks for the input guys. I won’t be using them.

Regarding re surfacing older lifters…… the set I pulled from the 400 all looked good, didn’t look like they failed or anything. I can post pictures later. My question is, would those be a candidate for re-surfacing? Is there something else to look for in a lifter to determine if it’s worth to resurface them?
