I did the timing and related components about a year ago, so I am going to start by saying it's not that.
The valves were not bent by inspection when removed for head resurfacing.

Video clip for sound:
YouTube Redirect

Things to note:
I use 93 octane fuel.
Head gasket is new.
Intake/exhaust gaskets are new.
Fuel injector O-rings are new.
Spark plugs are new.
All motor mounts are new.
Engine oil is past due but put a quart in recently.

Performance:
Drives fine.
The noise from the engine when I rev it in the video is annoying and present sometimes while driving.
