you can say the same thing on some of the tie-bar lifters, rivets snapping off, body failure go that route and it changes all the valve train geometry, different push rods and so on

thumbsSpeedy linked a GM #17120060 Delco H121.
That kit contains GM #17120061 Delco H122.
This note accompanies that kit.
• For single-service replacement lifter, use P/N 17120061
NOTE: These lifters allow more oil to the rocker arms than
the late-model truck roller lifters.
