It doesn't matter whether you count from the back to front or front to
back. The "rule of 9" will work either way.

Easiest way is to watch the rocker at the valve stem. When it quits
pushing the valve open, stop. If you go a little past, just back up a
"BCH" til it is at it's lowest point. Absolute precision is not a high
priority hear, as the "rule of 9" valve will be on the heel of the cam
lobe, and this is a relativly wide (in degrees of rotation) portion of
the lobe. So the odd few degrees you may be out on the open valve (from
abolute center of opening) is immaterial.
