Right side cam timing

I am following "the book"s directions for high-lift, high-duration cam timing starting on page 167. I have the left side timed and set at 2.3mm at .1mm overlapping tdc.

This is on an 83 sc with DR20 cams.

The book seems a bit vague on the crankshart-to-camshaft orientation, and where in the cycle to take measurements on the #4 cylinder's valve keepers...

1. The book says to set the dial gauge with 10mm of preload. THis doesn't seem possible with any combination of the short or long gauge extensions and the z-block.

2. The directions are unclear about whether to take the measurements on Cyl4 when Cyl1 is just opening, or when?

3. I see the references to having the "930" marking on the cam ends facing down to start with. However, I am not clear about the next section referring to the measurements.


Could someone pls point me in the direction or spell out a bit more clearly the procedure for the right-side cam timing?


thanks
