Edelbrock Victor CNC DR-17 Cylinder Heads 120CC Big-Block Chevy Engines

Designed for serious naturally aspirated big block Chevy combinations, the Edelbrock Victor CNC DR-17-cylinder heads deliver the airflow and efficiency required for maximum horsepower and torque. Featuring large 120cc combustion chambers, these heads are engineered for large-displacement pump-gas engines using a true flat-top piston configuration. The combination of raised intake and exhaust ports, revised spark plug location, optimized valve placement, and a 17-degree valve angle promotes superior cylinder filling, improved combustion efficiency, and increased power throughout the RPM range.

Each Victor CNC DR-17-cylinder head is cast from premium aluminum alloy and processed using Hot Isostatic Pressing (H.I.P.) technology to create a denser, more stable grain structure for enhanced durability. Fully CNC-machined ports and combustion chambers ensure exceptional consistency and airflow characteristics, while ductile iron valve seats and manganese-bronze valve guides provide long-lasting reliability in demanding racing and high-performance applications.
