Description

The Airflow Research Small Block Ford 165cc Renegade Street Aluminum Cylinder Heads are designed to optimize airflow velocity and combustion efficiency for small to mid-range displacement engines. With a 165cc intake runner volume tuned for strong low-end and mid-range torque, these heads offer improved throttle response and drivability, making them ideal for street-focused applications. Constructed from lightweight aluminum, they provide superior heat dissipation and durability compared to iron heads. These heads are capable of supporting builds in the 300-450+ horsepower range.
