Sounds like a bunch of locked lash adjusters, in other words, solid lashed valves.
I'm not hearing it either.
Hey Man, no reason to get bummed over it. If you did get a spare engine I would take the one you currently have and tear it down, find out what failed and why, then build it back up. Makes it fun when you can build one while you are still driving your car.

I would still pull the timing cover and check the guides. If the tensioners have failed you will definitely be able to tell. Shouldnt take you more than an hour or two to get it down that far and its REALLY easy.
