Default Identifying 2004 LS1 Motor

Just wanting to check if anyone knows the answer to either or both of the following;-
Where were the 2004 LS1 motors sourced from / assembled and how to identify one of these motors externally?
What piston deck clearance the stock motor has (ie amount above or below deck at TDC)?
I expect these questions ahave been asked and answered before, but I am new here, so just bear with me please.
Thanks,
Tintops

I'm pretty sure all LS1s came from Canada. The piston comes generally .008" to .010" out of the hole
