Oh that's so valvetrain noise. I'm with the others, pull the covers and measure the lash. It does not sound like piston slap or rod knock, I've had both and it did not spund like what you have.

You just need a feeler guage to measure the lash. With the covers removed turn the engine over by hand (socket and wrench on the crank bolt) until the backside of the cam lobe that you are measuring is next to the bucket. measure the gap between it and the bucket. 0.008-10 intake and 0.0010-12 exhaust should be fine. If they are larger than this then you ahve found the source of the noise.
