Nope- - - -it involves the "companion cylinder" method of determining TDC on each cylinder, before adjusting the clearance or hydraulic lifter preload on the cylinder halfway around the firing order from the one that's "rocking" This must be done six times, not just establishing "rocking" of the valves for #6. Here's a short synopsis:

Turn the engine CW at the crankshaft pulley until the #6 valves "rock"- - -exhaust closing and intake opening.

Adjust cylinder #1 valves (NOT #6)

Turn the crankshaft 120 degrees CW- - - -#2 valves rock- - - -adjust #5

Turn 120 degrees- - - -#4 valves rock- - - -adjust #3

Turn 120 degrees- - - -#1 valves rock, adjust #6

Turn 120 degrees- - - -#5 valves rock, adjust #2

Turn 120 degrees- - - -#3 valves rock- - - -adjust #4

You can precisely adjust all 12 valves with only two turns of the crankshaft (hot or cold engine) if you pay attention to the firing order and the movement of the rocker arms.
