Terribly noisy top end - Video Attached

[FAST380]

To start with, I put my phone right next to the headers and intake so the mic really makes it pronounced. With that said, it is really loud! Is it normal for a high lift cam?

I've owned the car/engine for 5 years and have always thought it was very loud, I guess I'm just now getting concerned. It also uses oil, but I beat the hell out of it and read LS1's use oil when abused? The engine was professionally built and has about 7K miles on it. Its mainly an around the town toy is why the miles are so low.

Oil analysis showed high copper and iron.
Video is too big so I have to link it to YouTube.

From those videos it sounds like a normal LS1. The passenger side does seem a little louder but that could be just the thin walled headers.
