If you look close the self align rocker goes down lower on the valve stem(has side walls if you will). The tip of the rocker is flat on the non self align rockers. With guide plates I would go with out. Hope I didnt make things worse:confused:

correct. the self-aligning ones have a cup to keep the valve stem centered in the rocker

thnx alot guys
