Yeah prob cause it's running leaner. Your tuning it normally at like 260deg or less. Heat damage would show bluing on the con rod just ask Rep lol. Rep or Sean could prob help more with what to look out for. If your seeing a loss in power order up a gasket + ring and get to work! Would make a good chance to check the condition of all your internals but I would wait til end of season and really beat on it til then.
