Renewing the camshaft bearings, and even possibly the camshafts themselves, if the lobes are worn and/or pitted, is a procedure that should be carried out during a general engine rebuild.
If you are only replacing the timing belt and pulleys, then close inspection of the camshafts and bearings is recommended?
