Matt---You didn't mention how many miles you may have covered since your last
valve adjustment. If it's been 12,000 miles or more, then it was time to take a
check on them. Most of the time the lash will grow, as wear takes place in the
valve train. It's possible that valve recession can cancel out the lash
increase, to some degree. Still, it's not usually a concern for most of our
engines if the lash is checked periodically.
The "thin width" feeler gauge is a good idea, esp. on rockers that have seen a
lot of service.
You'll want to check on the lash more frequently until you're sure that the
rate of recession (if this is what's occurring) is predictable. If you should
lose all the lash, this can cause burnt valves, should they not close all the
way.
