When you drained the oil, did it have a metallic color in it? When you swirled the oil does it have a very metallic element that is easy to see?
The shavings (if present) would be plainly obvious in that scenario. Do you have a compressed air gun that you might be able to use to blow the head a little cleaner so we could get a better look at it?
It also just may be build up of old stuff since the car hasn't been running altogether that often.
