Video/sound of my 383 engine

http://rapidshare.de/files/32620644/coldidle2.MPG.html

Is there any abnormal sound/noise that shouldn't be in the engine?? Especially in the bottom end. I trust your ears!

Valvetrain: 1.6 NSA Pro Mag. Rockers and Morel Lifters. (yeah a bit noisy)

there are lots of noises coming from that engine bay, but it's just too hard to listen to what's going on.

Thank you for downloading the video! I appreatiate guys! When I put the camera under the car, could you hear any weird sound? Or seems normal?
If I try to listen with stethoscope, would it help to figure out?

Rockers definately need adjusted.
May also want to check all over for exhaust leaks. I thought for sure I heard one when you went under the car.

It's really hard to tell from that video though.
You'll find them. Good luck.

Why did you say that? I adjusted them at 1/2 preload after 0 lash. (with engine without running method).

LT headers are noisy. But I will check if there is a leak or something else.

Rockers need to be adjusted and that's about all I can tell from that video.

So you also think my rockers make noise? Do think they are loose right?
