Is that posible?
The problem here is, the washers will lift the spark plug out of the cylinder too much. Thus keeping it out of where it needs to be
The way to go is by having the ground electrode facing 6 o'clock. This way it would block the flame from going into the exhaust valves instead of intake valves.

What about the guys comment about using the other side as the guide?
This really depends on where you decide to put the black mark. If you decide to put the black mark where the ground electrode is at then, it needs to face the exhaust valves.
If you put the mark where the spark plug gap is at, then you would need to face the intake valves.
I personally prefer using the first method. Because its easier to determine where to face the ground electrode.
