Re: 454 Heads
Guide plates are held down with the rocker studs. Torque the studs with red loctite to 50 lbs. The longer pushrods are for the exhaust valves (bottom ones). If the rocker doesn't line up properly on the valve stem, the guides plates can be cut and rewelded to correct the alignment.
A stock engine uses hydraulic lifters. The rockers are installed just like a SBC. Tighten the rocker nut to zero lash on the base circle of the cam then tighten the rocker nut 1/2 turn more.
