WOOT WOOT Sound from Front of Engine

I have just finished replacing the heads on my 2000 3.3 X, got her started up and have chased down and fixed my minor goofs. Car started up and runs fine, but for a strange "WOOT WOOT WOOT" coming from the lower half of the front of the engine. It's pretty low pitched as opposed to a squeak or squeal sound. My searches only come up with squeaks/squeals and grinds, but no WOOT.

The crank pulley/balancer is new, timing tensioner is new, all belts are new, so I'm at a loss as to exactly where this is coming from. The sound is in direct proportion to rpms.

The belts may be a wee bit too tight so I'll try loosening them up this Saturday, but in the meantime if anyone's familiar with this sound please let me know.

It didn't make this sound before the heads were replaced.
