These Crower shaft mount rockers are are designed to work with the All Pro '12' Series and Brodix BR7 LS7 cylinder heads. Both the All Pro and Brodix are great heads that we have used in many of our LS7 builds.
Once you get into big power, shaft mounted rockers are needed for dimensional stability and survivability. Crower has long had an outstanding reputation for craftsmanship and quality but there are a few other good name brands. The reason we selected Crower as our preferred LS7 shaft mount rocker arm system is because of their oiling system. These rockers feature an oiling hole at the top that provides lubrication for the wheel on the tip. Many of our engines see double duty as big-boost street and strip racers. The additional oiling on the top side can make a big longevity difference in a high mileage street application.
