We use this specification of cylinder head on most of our performance road (Sports Road) small bore engine packages. Specifically machined to work with the most popular performance camshafts in small bore Kent 266, Kent 276. The smaller bore sizes limit the size of the exhaust valve. Developed on an airflow bench and then on engine dyno/rolling roads to work with suitable compression ratios given modern lead-free fuel specifications. High quality lead-free exhaust seat inserts are fitted.
