To avoid confusion do this:
Choose a valve to be adjusted.
Turn the engine till that valve has opened completely, doesn't need to be perfect.
Mark the crankshaft pulley with chalk.
Turn engine one turn till the mark is at the same place, doesn't need to be perfect.
Adjust that valve.
Remove the chalk mark.
Lather, rinse, repeat for each valve.
This procedure can be used on nearly every gas or diesel engine produced in the past 100 years. The purpose of the procedures stated in manuals is to reduce the engine turning, but it adds confusion. The method I suggested above is actually better as it insures that the lifter is on the base circle of the cam and not just close enough.
