What you can’t see in this pic is there is also a spring relief cast into the body.
Notice the difference in the relationship between the adjuster cup and the roller tip between the two rockers.
The PRW rocker has the roller higher up vs the center of the shaft, so the rocker has to be rotated down farther for the tip to contact the valve, which results in the contact with the retainer.
