I noticed in your post that you removed "valve cover". Did you remove both valve covers or just the one? With these engines it's pretty hard to isolate a noise, because they are so damn noisy to begin with. Go get a stethoscope at a parts house and it will help you isolate the sound.
What's disconcerting is the engine stalled when the noise first appeared. That makes me lean towards a spun bearing, but you said you never went over 2500 RPM.
This may sound silly, but check your spark plugs. A loose spark plug will give you a sound that you swear the engine is going to disintegrate.
