Rattles

My 2005 c6 vert has started to make a rattling sound from the engine when I first start it cold. Seems to go away when warm. Is this normal? Thanks for any help!

Not much to go on. Mileage, and perhaps if you take a video with sound clip, that would help.
Some possibilities:
1) Main belt tensioner bearing
2) Harmonic Balancer starting to wander
3) Bearings or brushes worn in Alternator.
4) Worn out drive or AC belt

Earlier LS motors had a problem called piston slap. It made the motors sound like a diesel for around 30 seconds to a couple minutes on cold starts. I don't know if the LS2 suffers the same problem?
