Jerry, I agree the Tech Tip needs to be updated. I found one of your previous posts showing this technique.
A simpler, and more accurate way is to use the "companion cylinder" adjustment method. When one cylinder is on top dead center of the compression stroke with both valves fully closed, there is another cylinder that's on top of the exhaust stroke with both valves slightly open. The exhaust will be closing, and the intake is opening. That's called "rocking". The companion cylinders are:
1&6
2&5
3&4
Take the firing order, 1-5-3-6-2-4 and cut it in half:
1 5 3
6 2 4
The companion cylinders line up above each other. Roll the engine over until the #6 cylinders are rocking, and adjust #1. Rock #2, adjust #5. Rock #4, adjust #3- - - - -etc. All six cylinders can be adjusted in two turns of the engine. The easy way to do this is to put the transmission in high gear and gently roll the truck forward to line up the next cylinder's valves.
