The designation refers to a specific cylinder head design, likely employed in high-performance engine applications. “270” probably indicates the head’s intake runner volume in cubic centimeters, suggesting a high-flowing design suited for larger displacement or higher RPM engines. The “22” is likely related to a valve angle or a similar measurement critical to combustion chamber geometry and airflow dynamics within the cylinder head.
Such components are crucial for optimizing engine performance metrics such as horsepower and torque. Enhanced airflow characteristics achieved through careful design improve combustion efficiency. Historically, modifications to cylinder heads have represented a significant avenue for extracting additional power from internal combustion engines, evolving from basic porting techniques to sophisticated casting and CNC machining processes.
