When Johnson stopped making the tappets a few years ago, I would take worn original lifters, measure the O.D. , hardness test them, and then resurface the face and parkerize them. Seems to work good for me.
I have heard the Johnson tappets quality is back to normal. But I do not have direct experience to prove it.
What camshaft casting were you using for the tests?
