The heads have to come off to replace the lifters and it could be a bad lifter. Have a pro look at it for sure

I fixed this problem on my truck by changing the Oil Pump Inlet Tube O-Ring. The lifters are the first part that don't get enough oil after this o-ring breaks down. All Chevrolet mid 2000s era 5.3L O-Ring fails around 150-190K.
