gm 3.1 and 3.4 spark plug order and cylinder location

hello during the spark plug service many people get confused on exactly which cylinders are which and i hope this posts alleviates it here is a picture below for reference.

cylinders 1 3 and 5 are near the back fire wall and cylinders 2 4 and 6 are near the radiator cylinders one and 2 start from the belt side or passenger side of vehicle. hope this helps

many of these questions get asked from my repair video on changing the spark plugs from this engine
