Sportsman Steel Options Our Rocker Story When Chevrolet introduced its small-block V8 in 1955 one of its highly praised features was its lightweight stamped steel rocker system. With little more than a factory Duntov solid lifter cam a 7,000rpm redline was realistic. This economic valvetrain had its limits though. As long as mild seat pressures of around 100 pounds were used with low-lift hydraulic or flat tappet cams, life was good. As aftermarket cam manufacturers started grinding higher lifts, the rocker’s shortcomings began showing up. First, the rockers bottomed-out on the rocker studs because the slots were too short, then as spring pressures increased the studs pulled or broke out of the head bosses. The fixes came both from the aftermarket and GM.
