Sometimes information on the cool stuff has to be dragged out of folks manning the booths at PRI, but we get the details nonetheless. We found these shaft-mount, Harland Sharp (www.harlandsharp.com) rocker arms at the back of the company's display. The rockers are made specifically for Edelbrock Victor small-block Ford cylinder heads, but can easily be retrofitted to work with Victor Glidden heads (by milling 0.100-inch from their base). The system is completely bolt-on and features offset intake rockers (to accommodate for the offset in the heads), a solid shaft for better stability, and enough clearance to work with gigantic 1.687-diameter valvesprings.
