Ppp lifter have a coated lifter with a coating that is safe for a cast cam. In my spare engine I took out the shubeck grenades and installed them on a cast cam. Broke them in as if it was a new cam and lifters with break in oil. Valve setting never moved. Took them all out after to inspect them and they looked like they came out of the box.
