Noise: What is 'normal'?

I put 500 miles on my truck this weekend and had a chance to listen to it real good. I hear what I want to call a lot of top end noise under load. It sounds like cam lobes hitting lifters or maybe valves - kind of a rattling type sound. I'm curious if this is considered normal in a 7.3.

From the description, it sounds normal. These things make a whole lot of clatter and clacking and such.

What I notice is ticking and clicking and stuff seems normal. No squeals allowed tho'.
