The way to adjust valves in my book,unless you have a huge cam.

Adjust #1Cyl when #6Cyl is in the rock position Intake & exhaust rockers arms are both moving.

Adjust #5Cyl when #2Cyl is in rock position.
Adjust #3Cyl when #4Cyl is in rock position.
Adjust #6Cyl when #1Cyl is in rock position.
Adjust #2Cyl when #% Cyl is in rock position & so-om.
Hope that makes any sense.
Do it this way takes less turns of the crankshaft to adjust all you rocker arms.
Hope that might help someone.
