Sounds like the noise went away with the valve cover off. It also looks like they have been hitting the valve cover. Do you have any noticeably loose rockers or rocker studs?
Welcome to the CAC.
That first video sounds very much like a loose rocker arm. If you have a piece of hose or even a broom stick, put it to your ear and run the other end along the valve covers to determine which side it's on. It should be very audible. Next step would be to remove that valve...
