here is a pic.

now back to the question at hand, How to check the used roller lifters to see which ones are all right and which ones need to be replaced?
With any lifter new or used, you puts down your money and takes your chances. Unless really gouged or gunked up inside there really isn't much to learn by taking them apart, and usually doing that to clean them is a 50/50 proposition that a perfectly good lifter will be made into junk by the time you're done. So you need to decide what is the risk against the cost of replacing a lifter or two after the engine's assembled and installed.

Given a new set of GM roller lifters can be had for 120 bucks, it seems the cost and effort of digging a failed lifter out isn't worth the risk of unknown used lifters.
