It is normal for hydraulic lifters to “bleed down” show a gap sitting . Whole idea is not to have to set any precise clearances , — does not matter when oil pressure comes (assume valve is closed) lifter expands up , giving zero clearance . When valve starts to open , a check valve in lifter prevents that oil from squeezing back out ,as pressure inside is far higher than engine oil , as it lifts valve . It loses a tiny bit by design so it can track changes , over and over in gap as engine warms . In chev , where they inherently have adjustable lifters with hydraulic ( screw mounted ball rockers ) they adjust to zero then “ one turn more “ so lifter is like .030-050 down ( can be more) to allow the above action . Chrysler on B block controlled stuff ( tolerances) so just “throwing together” on assembly line the lifter should be somewhere in the middle of travel no checking or adjusting needed . Unless someone messes with it / non stock parts . Note base circle of cam is important to this , so reground cams may need longer pushrods etc All is good if no loud clicks ,or ticking , (indicates one is stuck ) I have found mobil one frees up stuck ones . Sometimes takes 3000 miles. Good stuff ymmv !
