the oil pressure is at 50 pounds hot. i had the heads on the ls1 first with no problems but when i put the heads on the 6 liter it started doing it. i was listening to last night and it sounds like one of the lifters or something is making the noise not all of them nut its got new anti pump up lifters and good valve springs and a mild cam, not rear sure. i hope its not the lifters dont want to pull the heads off
