The sound is definitely something to do with the valve train. The first thing to check is the Cam Chain Tensioner. They are pretty cheap so I would just buy a new one test it out. Past that it could just be the valve clearance could be too much.
Has this sound started all of a sudden or has it gradually gotten louder?
