In order to take off the valve covers on the cylinder heads, loosen the rocker arm shaft bolts by first unbolting the middle ones to outer ones. Fully loosen the bolts and pull up rocker shaft assembly from off of the cylinder head. Keep track of rocker arm positions and store each set of rockers so that they can be reinstalled in their original positions. Remove push rods and store them in a way that prevents mixing them up at installation time. When examining the rocker arms, search for wear, cracks, and other types of damages particularly where it comes into contact with both pushrods as well as valve stems. Similarly, look at the rocker arm bores and shafts for any signs of stress cracks, galling or wear patterns that are not usual. Any worn out or damaged parts should be replaced with new ones including installing new shafts as well. Make sure there is an opening at each end hole part of all rocker arms' pushrods. Examine push rods for end cracks excessive wear; also check them by running across a plate glass to see if they are bent or rolled. To lubricate lower ends before replacing in lifter socket put clean engine oil or engine assembly lube on lower end of each pushrod; this will ensure that they seat properly in their original places when installed again.Apply some engine assembly lube to protect valve stem ends and upper portion of stem from damage during initial start-up process. At first lubricate most components present on top sides such as upper ends for push rods together with valve stem bottoms using either pure old engine oil or brand new motor assembly greases hence avoiding knocks while starting up your vehicle for instance Rocker arm has being fully oiled using either just refined old motor oil or absolutely unused motor grease with complete assemble back onto cylinder heads through which it is expected must have gone through full application treatment.Tighten center bolt first then followed by center right bolt, center left bolt, outer right bolt, and finally the outer left bolt for rocker arm shafts. Tighten bolts, making sure that as the tightening process is proceeding push rods are properly seat in rocker arms. If such conditions develop where rocker arm bolts start becoming tight before shaft has been completely seated or else push rods are binding; all rocker arm shafts must be removed followed by totally checking all components before taking next action. Lastly install valve covers and start the engine to listen for unusual sounds from valve train and observe oil leaks at valve cover gaskets.

Check for wear, cracks, and other damage, particularly where the pushrods and valve stems contact the rocker arm.

Inspect the pushrods for cracks and excessive wear, rolling each across a piece of plate glass to check for bending.

This is done to prevent damage during initial start-up.
