Close-up down onto an installed cylinder head with the valve cover off, showing three polished aluminum roller rocker arms on studs with black poly locks and pedestal mounts. The cast head surface carries raised casting numbers, and gold-cadmium and black hex bolts sit between the rockers along the valve cover rail.
