I attached the procedure for adjusting the valves. Very simple and take your time.
All the push rods are the same length so you can install anywhere.
1. Remove rocker arm cover.
2. Rotate engine until mark on torsional damper is aligned with "0" mark on timing tab fastened to crankcase front cover. To ensure engine is at No. 1 cylinder firing position, place fingers on No. 1 cylinder valves as the mark on damper approaches the "0" mark on timing tab. If valves are not moving, engine is in the No. 1 cylinder firing position. If valves are moving, engine is in the No. 4 cylinder firing position and should be rotated one revolution.
3. With engine in No. 1 cylinder firing position, adjust the following valves:
Exhaust valves 1, 5 and 6.
Intake valves 1, 2 and 3.
NOTE: Even numbered cylinders are in the left bank and odd numbered cylinders are in the right bank, when viewed from front of the engine.
4. Back off adjusting nut until lash is felt at pushrod, then tighten nut until all lash is removed. This can be determined by rotating pushrod while turning adjusting nut. When all lash is removed, tighten adjusting nut one full additional turn to center lifter plunger.
5. Crank engine one full revolution until mark on torsional damper and "0" mark on timing tab are again in alignment. This is the No. 4 cylinder firing position. With engine in this position, adjust the following valves:
Exhaust valves 2, 3 and 4.
Intake valves 4, 5 and 6.
6. Install valve covers and related components, then start engine and check timing and idle speed.
