The correct valve lash setting is: intakes,.010 to .012. Exhaust: 014 to .015 I assume you are using adjustable lifters. If they were not locked properly after adjustment, that could be your problem. We always replace all valve springs because they can take a "set" when older. One weak spring can allow the "tic". When we ground valves years ago, including the stems, it always seemed to create a ticking sound when one or more if we cut the stem a bit too much. As to the removal of the pump rod, it is better to leave it in place because the bushing will allow an internal oil leak. The pump rod rides on the camshaft and the hole extends into the camshaft oil gallery.
