I got those lifters from EGGE they were just tossed into a box, and nearly every one of them is nicked up, to such an extent I didn't even bother using them. Much like the rod bearings I got from EGGE, they were just stacked together in a pile, They may have good stuff, just need to get a better shipping department. I ended up getting a set of lifters from NAPA, They seem to be working fine, I have no idea what the exact composition of them is.
