The stamped numbers are probably not dates. > And if I do go new valves what do I have to do to allow the engine to run on > unleaded??? I can find anything on this in the Muir/Chilton and Bentley The OE setup is fine with unleaded gas. Avoid suppliers that offer to upgrade you (for a price) to an unleaded configuration. The important points of the OE setup is that the valve guides be bronze (not cast iron) and that the intake valves ( I think it's the intakes) be the more expensive ones with the chrome plated stems. The older non plated valves are still available, but they should not be! Beware of this false economy!
