In the first video it seems like I hear a loud couple of 'clack clack' noises as the engine comes down to idle speed, then around :57 or so it sounds like the clacking became more consistent as the engine idles.



VTEC pins (between rocker arms) not releasing fully, or sticking?
Valve adjustment?

Your car rev sounds odd. The click clack may be your IACV engaging and disengaging. Test by disconnecting the harness and see if the sound goes away. It wont hurt your engine but will make the idle fluctuate. I also noticed you do not have a CEL "ON". You have a swap on the head that is a Z6 so I would check and see what ECU you currently are running. Does your car drive with hesitations/sputtering at low rpm when taking off?
