Sounds like an exhaust leak. Possibly coming from your headers. Is it coming from one side of the engine? Hard to tell in the video. May be worth it to replace the header gasket.
Yeah just coming from the drivers side. And I just got new headers put on with head gaskets and kinda when I noticed the noise I did hear that the hg bbk gives you didn't last but damn you think that quick?
Yeah I tried tightening them up. But that didn't take away the noise.
It sounds like you have a lot of things going on there.
You might have a slight header gasket leak but what I am
hearing mostly is valve train noise. What rockers are you running?.
If they are adjustable then I would consider going over them
again rechecking the valve lash.
