M117 560 loud valve noise

I have not ruled out the possibility of an exhaust leak. I see nothing, but the valve noise is on both sides and pretty balanced.

But it could be normal maybe? Anyone have some audio of a 560 running?

I did remove the valve cover tonight for inspection and all looked well. What I think is normal scoring of the lobes. I will post pics.
