I have heard a similar noise before, but I can't put my finger on it. Is there a spark plug out or loose? Is the header leaking where you have removed the A/C compressor mounting brace, or anywhere else?
RACE ON!!!

That would be a waste of time, unless you will be in the process of tearing it down. If something were on top of a valve, it would either drop into the cylinder when the valve opened, or it would jam between the valve and the seat causing a massive miss. If there is something in the cylinder, you won't reach it with a magnet. If something you dropped didn't get into a cylinder, it wouldn't be causing that noise. Simple logic.

Anything but a nut or something down the hole!!!! Thanks for the encouragement.
I was thinking, and remember, I'm not in a clear state of mind, that the nuts I used to secure the SR were too big to drop past the valve and got caught on the top of the valve and may be getting smacked around the top of the valve, in the head.

Its not something in the cylinder, has a mechanical sound as if its keeping rythym. Valvetrain somewhere. Let it run longer and see if oil comes out...Do it anyway.
Edit: Kind of like a lifter that isnt pumping up.

Any way to test that?
Watch the rockers, they all move full throw.......if the lifter was bad, why would they move?

The oil pumps up fine, I'm afraid to let it run up. Lifter, however, interesting call. That does sound somewhat reasonable...I put in new lifters to avoid such a problem..

Right, and they wouldn't rock....no loose rockers. I'd give my left nut for a loose rocker right now....
All my common sense is out the window right now....I'm just too dam close to it...I have to drive seven hours tomorrow, lots of time to think.

Something in the valvetrain isn't right. How long have you run the engine so far? Reason I ask, is in my book, there should still be some visible oil on the heads. Even if it has been a few days.

The car sat for two weeks, then I started it and got this noise. I only started and ran it for short bursts like that after hearing the noise.

I'm using Mobil1 20-50. 15K oil.
Should I drain and re-fill?
This is really loud. You think I'm just not letting it run long enough? I'm afraid to do that.
