curious about valve lash setting/check

Screenshot_20191125-182355.png I know everyone has their method of adjusting valves,
But this is the simplest way I know of and works be it a Chevy or Mopar. (Same firing order.)
And only two places to set them.
TDC firing #1
TDC firing #6
This is from a mercruiser manual
Also in the boat world engines are viewed from the rear so a standard rotation engine is left hand, just if someone is unaware.

Not sure why pic. Is blurry
But they start on #1
Then turn crank 1 turn to fire #6
