Help me figure out this engine noise

[Skraight]

I'm having issues with my motor right now. I took a video of the sound in hopes that someone would be able to help me out as to what it could be.

The noise is louder at lower RPM's and seems to quiet the higher the RPM's go. No power loss or any difference in the way it runs. I originally thought it was the timing chain guides, but me and a friend pulled the valve cover and they are all removed already.

Here's the video, take a listen and let me know what you think. Thanks for your time.

Here are the engine specs in case it matters:
KA24DE-T
Wiseco 9:1 pistons (0.20" overbore)
Eagle H-beam Rods
ARP Head, Rod Studs
Cometic 0.040" MLS head gasket
Block and head decked

Tried to embed it but don't think it's working, here a direct link http://www.youtube.com/watch?v=d6MKeIJeEz8

you have no timing chain guides at all? how does your motor still run without them?

Well the top and side ones have been removed.
