I have a feeler gauge that has a .002" step ground in all the tips- eg. the
.010" has an .008 step, so you can do go/ no go tests quite easily. If
you need .010", select the blade with .011" and .009". When the tip (.009
) passes and the unground part (.011) jams, you are pretty close to the
desired #. Not a precise measurement, but there are likely to be a range
of unknown clearances ( eg. rocker shaft, oil film thickness, etc.) in the
valve train which are at least as large as the +/- .001 uncertainty the
gauge allows....

Feel is better gained by experience than by description. What you're after
is
having the lash set correctly so try this method and then you'll be on your
way
to feel. Lash the valves so that the 0.010 feeler gauge goes between the
rocker arm and the valve but the 0.011 feeler gauge doesn't. Note: erring
on
the side of looser is better as they tend to getting "tighter" as the engine
breaks in.

OK, OK, sounds like a stupid question. But can anyone
really describe how it's supposed to "feel" when you've got
the valve lash set correctly? Should the gauge slide in
with very little resistance, noticable friction, or
just-barely-fits-without-buckling?
I and my valves thank you. (mostly the valves)
