To add to George's post, there are two different 'stud girdle sets'. One supports the main bearing 'studs' while the other supports the rocker arm studs. I run the second type-(Ridgeway)- on my A-3s for insurance against breaking valve springs. They are a 3-bar type that fits under most aluminum rocker covers with a minor bolt-swap. Ridgeways are no longer available, but there are copies around from Jo-Mar. Note- the 'Grand National' size will NOT fit under most rocker covers!
