To clarify Flatpac6,
To advance the camshaft timing less than allowed by the pin holes, you jump the camshaft chain one or more teeth at the camshaft sprocket so the net result is the sprocket has turned counter-clockwise (CCW).
To retard the camshaft timing jump the chain such that the camshaft sprocket has moved clock-wise (CW).
You'll then reset the pin into a different hole to get the correct timing.
Remember the camshafts rotate CCW while the crankshaft rotates CW.
10 camshaft sprocket teeth equal the difference of moving the camshaft pin 1 hole.
Each camshaft tooth equals 1/10th the difference you get with 1 pin moved 1 hole.
This will allow you to time the camshaft exactly to whatever position you desire.
There is no need to accept one camshaft timing different from the other because the pin holes straddle the desired timing.
The Porsche engineers designed this ingenious process, they would accept nothing less than perfect camshaft timing. Nor should you.
Feel free to ask more questions.
