After having intake gaskets changed a year ago on my '97 5.7 Vortec, I decided to send an oil analysis in once I put some miles on it and a couple oil changes. I changed the oil in October with only 500 miles on it, second oil change (possibly third?) since they changed the intake gaskets. I got the result back, which is below, showing I had a tad bit high lead in it. I run Mobil 1 5w-30 synthetic in it and don't drive very far with it. When I do drive, it's maybe three miles tops in a day. The oil that was used in it after the gaskets was some sort of Kendall.
What would be causing this high reading of lead in such short of time? Are my bearings going? And any thoughts that the coolant readings could be residual from the gasket change? Coolant is a hair low from what looks like an external leak, but I want to pressure test it again over winter break.
Edit: Since it won't let me upload a clip of it because the forum has changed something...

Second Edit: Since I figured out my Google Drive, here's the complete report with their blurb about the leadhttps://drive.google.com/file/d/0Bz89WRgQhBE-aUx2SFhwaWp5RjA/view?usp=sharing
