Can not remember why, but the other style with where the adjustment is held via threads being an interference fit are preferred. If yours are OK and holding proper adjustment, you should be OK.

There are other factors to consider if you decide to change them. The shoulder of the tappet has to be proper size against your cam.

Have you tried searching here for additional info?
