This is kinda fuzzy and I could be wrong, but I seem to remember a small block plug (like a miniture freeze plug) in the right oil gallery at the back of the block. It's at about the same height on the block as the passage for the barbell, but on the other side of the block. Maybe that plug was left out.
Can anyone confirm this - or correct me if I am wrong?

I had the exact same problem.. I started my truck without the valve covers on, and there was little or no pressure from the ls6 pump I installed. There would be loud valvetrain noise that would come and go.
I changed the o-ring on the oil pump and it went away.
Here are side by side pics.
