The bridge design just lower manufacturing cost. The bridge keeps the top part holding the rocker arm down from twisting. That part is made to guide the rocker itself, preventing it from twisting. No guide plates or special installation methods are needed -- just drop the rockers on and put a bridged top on, tighten, and go to the next one. The rockers have to be straight -- no need to give them a second thought.
