320 and 325 rockers are the same.
Check cambelt timing and inlet side air leaks.
Does your engine have the distributor on the front end of the camshaft, or is it an early one?

If plugs are sooty lack, the engine is running too rich.
Does the engine start OK from cold, then begin to run progressively more roughly as it warms up?

Is this a new problem, or one that's been there since the rebuild?
