My bad. I didn't catch the statement on noisy lifters. If the filter is plumbed inline so all goes thru the filter before going into the lifter galley port then that could be an issue causing the lifter noise. Packard did make several changes with filter types and finally changed the plumbing route to feed the lifter port directly because of noise.

As you said, after all these years It is strange the plumbing should suddenly appear a problem. If it is inline, unless a filter is completely different or something got into the line and blocked flow it should still work as before. Another question -- When you did the valves did you use the gauge and grind off the stems for the changed clearance? I wonder if the valves could be not seating fully -- but again, strange it would take 200 miles to show.
