The method I suggested is the SAE method and works for all cams.
The method Tom Monroe shows is the same as the factory manual and
only works with cams of little or no overlap. If your cam has a
decent amount of overlap, all the valves must be set individually
when the lifter is located on the base circle of the lobe. At
that position, the valve is closed and there is no lift taking
place. If you have zero overlap, the factory manual approach
will also do that. However, addd in overlap, and that won't
necessarily be the case. It's always best to watch the valve
motion and chase the firing order. IIRC, you had some problems
with setting the lash on your Comp 282S. Using Monroe's method
may have contributed to that.
