Cliff----If the rocker wear is where it contacts the valve stems, you
can get a more accurate lash adjustment by doing what you were
advised...by snipping a feeler gauge to a little less than the width of
the stem.
There is a limit to how long you can use this method, of course. If the
shaft is worn where the rockers pivot, then rocker placement at the pads
can vary.
When the pad grooves become as deep as the lash, there's a possibility
that the stem tip(s) won't always find the groove, and the valve willl
not shut when its time..
Removing the step from the pads is another option. If you do this, try
not to disturb the work- hardened area where the stems have been making
contact.
Most of these shafts are only case-hardened, at best. Once wear starts,
it seems to accelerate.

Getting my 6 ready for spring, still snow on the ground here in
Montreal, I removed my rocker shaft to inspect it and found that some of
the rockers are worn where I can feel a noticeable wear by dragging my
fingernail over the wear areas. Some are worse than others. How does one
know when a rocker needs to be replaced. Someone told me to grind down a
10 thou feeler so that it would fit in the wear area of the questionable
rockers when adjusting ? Any help would be appreciated.
