Not sure about noise...
 

At idle, I have a defined tick going on that gets faster when you rev but doesnt get louder. I feel no power loss and nothing negative, yet the noise makes me wonder what it could be... Any ideas? Should I switch to a different oil or anything like that?

mayb piston slap or a collapsed lifter?

its pretty common on ls1's

No, I'm an idiot. I found an exhaust leak.

Thats what I was getting ready to say. I had the same problem. I thought it was something in the valvetrane but was a exhaust leak.
