It?s no secret that increasing airflow to your engine can be the biggest single improvement you can make to produce more torque and horsepower.The key to making excellent torque and horsepower comes from using the smallest port for a given amount of airflow and then matching the correct port size to the airflow requirements of your application. It is extremely important to have this relationship working properly, as engines can only consume a nominal amount of air.In order to cater for the variety of engine combinations our customers build, we are continuously expanding our cylinder head range with more port configurations than all other Cylinder Head manufacturers put together, to ensure we have the correct one for your specific application.
