Rattle in '94 9000 CSE, valves?

I have a '94 9000CSE with 184,000 miles. Very clean, running fine, however it rattles when accelerating. I bought the car used. I don't know if the timing chain has ever been replaced. I am assuming the rattle is either the valves or the timing chain, although I suppose it could just be knocking.
I think the ECU is supposed to detect knocking and respond, primarily with a timing adjustment I assume.I haven't tried higher octane fuel. I suppose that might work if the problem is knocking.
Otherwise, any good ideas on distinguishing tapping valves from a worn and rattling timing chain?
