Sound like Carbon Build-up to you?

Howdy,

Check for a bent valve, broken valve spring, bent pushrod, or broken rocker arm. You will probably have to loosen the rocker and spin the pushrods one at a time until you find it. If you find a pushrod bent, inspect it's valve, spring, rocker, and lifter carefully.

I think you will find a bent valve sticking and then eventually freeing itself until it rotates around to the same point again. The valve guides wear oblong so a bent valve will jam in certain orientations. That is the only thing I can think of to explain an intermittent knock.
