New Small Block Stroker Engine Noise

Bill, I watched the video before reading your comments and noticed the noise you mentioned. Have you run it any more since the oil change? I'd like to crack that filter open and see what's in there. If you do run it again, can we get some video at the exhaust end?

This exhaust video was taken at the same time as the other video:

I have the oil filter from when the oil was changed after 20 minutes of run time. The oil that cam out of the pan had a slight trace of silver in it, very slight, which I would think is normal.

When the engine was on the stand I adjusted the valves 1/2 turn past zero lash. This was done with the intake off where I could watch the lifter plunger get depressed. Would one full turn past zero lash be better?
