Sounds like a loose rocker...did you tighten the rockers that were "off" the cam and then rotate engine and tighten the ones that were "on" the cam before rotating?

Agreed. Sounds like a loose rocker. Easy fix.

Go back and make sure you torqued all the rockers to correct specs. Make sure the pushrods are seated properly also

I removed the valve covers and found this. Is it normal and could it cause the knocking?
