well i just did a rebuild on my stock ls bottom end, new main and rod bearings new, oil pump, water pump, etc....

well i started my car up and drove it for 100 miles and it started to make a tapping sound like it was a rod nock sound but it didnt come from the bottom end, it mostly sounds like its coming from the head, i checked the oil for metal shavings didnt find any so idk what else to do, i just took out my cams but didnt find anything interesting of where the sound would come from
