Sorry for the double post, but I'm going nuts here
not to mention the fact I have a 5 1/2 hour drive to Indianapolis tomorrow.

Is it coming from the front of the engine or somewhere else? It almost sounds like a bolt on the torque converter (if it is auto) or flywheel hitting on something. If it is coming from the front, might remove the belt and try to determine if it is one of the accessories that has a bad bearing. Hard to tell with these little bitty laptop speakers.
On another note, what brand of headers are those?

Also, pardon my noob-dom, but what is "piston slap?"

OH MY!!! This is completely dumb and not going to help you at all but the little blue guy jumping up and down in your post is jumping at the same tempo as the noise in your video. It looks like he's dancing the the beat
Sorry

Piston slap is when the piston is too small for the bore and the piston skirt hits the side of the bore as it rocks back and forth. The sound is not loud, kinda like a lifter but more tinny.
The piston hitting the head will only happen once or twice and then engine will no longer run. When the rod bearings go out you get a knocking sound that is caused by the rod clanking on the crank as the crank pushes the piston up and the burn shoots it back down. The sound is not good but can last for long time before the engine dies. When the bearings go the piston usually does not move up as high as it should, so it hitting the head is unlikely.
