Take the aux belt off to eliminate any noises from air con/alternator/ idler pulleys.
The crank case valve on the top of the engine are a GM stock item and can make strange noises come from the engine.
Loosening the oil cap while running ( keeping the cap in situ) to see if any noises change.
All cheap to try.
