Is my LS1 knocking?

Here's a video I took of my 1997 Corvettes LS1 idling. Does it sound like its knocking or is this normal engine noise? Thanks.

No knocking.

Quit worrying and trying to hear a knock, you'll make yourself sick.

Sounds normal. Maybe a small leak somewhere?

I recently swapped B&B exhaust from my 98 to my 97 and I had to reuse 2 of the 4 flange gaskets because B&B doesn't make them anymore and I couldn't find them at any part store. I thought I put enough liquid gasket sealer on both sides and I went back recently and re-torqued the bolts to 37 ft. lbs.

Perhaps there is a small exhaust leak echoing through the aluminum block? And thanks for putting my mind at ease everyone.
