All rockers seem to be getting good oil flow.
Did you turn the motor over without plugs in it yet? I'm wondering if maybe you should take the plugs out and turn it over by hand to see if you can feel where it might be "catching" and listen to the possible source of noise. That will eliminate all other background noise. Good luck.

If you dropped a valve it would be hammering away. The plug might give you some insight if its off color of has metal flake on it.
