SBC SHP Cylinder Head 180cc/64cc SP - Bare

The DART SBC SHP Cylinder Head 180cc/64cc SP - Bare is purpose-built for serious small-block Chevrolet engine builders and street performance enthusiasts seeking maximum airflow and combustion efficiency. This bare casting serves as the foundation for high-performance street and mild competition builds, offering excellent value when paired with your own valve train assembly. Whether you're rebuilding a classic muscle car or modernizing a street rod, this cylinder head delivers the flow characteristics needed to unlock additional horsepower and torque from your SBC platform.

The 180cc intake runner volume and 64cc combustion chamber are meticulously designed to balance cylinder filling with efficient burn characteristics across the RPM band. DART's engineering provides superior port geometry that reduces turbulence and promotes laminar flow, directly translating to improved volumetric efficiency and throttle response. The bare casting arrives without valves, valve seats, or guides, allowing builders to specify premium components tailored to their exact engine combination—whether running stock-style hydraulic lifters or upgrading to roller assemblies. At 20.6 lbs, this head is a substantial component engineered for durability under sustained boost or aggressive naturally-aspirated tune.

This cylinder head is ideal for small-block Chevrolet engines from 283 to 400 cubic inches, making it compatible with both vintage and modern SBC applications. Installers should verify deck height, valve stem length, and pushrods during assembly to ensure proper geometry and clearances. The bare head format is perfect for builders who want to invest in premium stainless steel valves, performance springs, or custom valve angles. Proper porting and matching to your intake manifold will maximize the head's potential and ensure your engine realizes its designed output across your target power band.
