I would still suggest you make sure the mechanical and vacuum advance are both working. Just checking base timing would get you to pass at idle but at speed, if the advances are not working correctly, you would fail. You could still have a bad pattern on an injector too. The combustion chambers could also be carboned up causing high combustion temps and high NOX. It is not common for a CC to go bad but maybe someone hollowed it out or overheated it with a too rich mixture.
