TEA-20 and NO Timing Marks on new gears

Now I am looking at an old cam timing gear and describing this will be tricky...OK there are four holes where it bolts to the cam, and then four outer holes that hold the weights. If you look carefully at the four outer holes, you will see that they are all in slightly different places relative to the tooth points. Find the one that lines up closest to the point of a tooth. The timing mark is one and a half teeth counterclockwise (looking from the weight side)from there i.e. in a valley.
To confirm which bolt hole this is: on mine, there is a small hole (maybe for oil drainage) very near the bolt that is across from the bolt nearest the timing mark.
Whew.
Now once you have the crank gear on, rotate the crank until the timing mark on the gear is pointing at the camshaft. At this point you will have to rotate the cam to ensure the valves are in the right place and bolt on the timing gear with the mark pointing at the mark on the crank gear. Read the manual a lot as I think it's beyond me to explain it without actually going through the motions on an engine.
Maybe someone else can help with the rest?
