That brings us to the topic of rocker arms, the factory FE shaft-mounted versions, of which are hampered by the fact that the outboard (exhaust) rockers at either end of the shaft are unsupported-cantilevered-and tend to break off when dealing with heavier valvesprings or high-lift cams. There are different stop-gap solutions available, but for something like his 445 stroker, Barry likes this roller setup from Erson. These have billet bases with full shaft end support and mount to the same points on the head as factory rockers. View Related Article
