Rhoads Lifters On Solid Lifter Cam - Setting Valve Lash

Did you run the Z-Max lifters or the original Rhoads? Two different animals. We're talking about the Z-Max. They are fairly new. Completely adjustable, whereas the original Rhoads lifters were not.

This was in 1990 so I imagine they were the originals. Still have the box I think... yellow/orange/black graphics with a swishy style ?
