if nothing has been done with cam bearings and was oiling before cam change...
early small journal blocks have to have groove/flat spot in cam...pull lifter and spin drill and see if oil is flowing out of oil galley in lifter bore
if all that is right look at lifters... pull lifter apart and you should see a clear path for oil to pass and go through pushrod seat..
there will be a disc(valve) that sits against bottom of pushrod seat and there should be away for oil to go between disc and pushrod seat. it may have a embossed/raised place stamped in disc with a small spot that isn't embossed,leaving a small groove for oil to pass. some have the bottom of pushrod seat curved, both styles I have seen not oil.basically the disc seals against the bottom of pushrod seat and has a small place for oil to flow through.. if it does'nt which is a defect I cut a small groove in bottom of pushrod seat so oil can pass between disc and pushrod seat to oil pushrod/rocker..
lifter should have oil hole on outside in the groove,have seen them missing...
if hole is in body above oil band then it wrong for hydraulic
