Hi Pete, if you buy the ORIGINAL "Johnson" tappets you'll have no issues, under no circumstances would I buy any "Johnson-Style" ones!

We haven't had a single "bad" OEM "Johnson" lifter since we began using them back around 1980 or so, not one!

Thanks, Gary in N.Y.

P.S. Most up here have no real way to check "hardness", BUT, everyone can check the adjusting nuts for "flatness", the "Johnsons" have a radius on the nuts where they contact the valve tips. This isn't a "fluke", it's part of the design to make the lifters actually function correctly! If the nuts are flat on top avoid using them!
