If it was a connecting rod or wrist pin problem it would get faster when you rev it up. Is it a loud knock at idle or a loud tick? If it is coming from the cylinder head it sounds like a lobe on your cam shaft might be worn or a rocker arm is worn down. You know you can adjust the valve lash on the valves, that might work to. I am just trying to give you the cheapest solution first. Let me know.
