SBC 180cc Alum Cyl Head 64cc 2.02/1.60 A/P Bare

The FLOTEK SBC 180cc Aluminum Cylinder Head with 64cc Chamber (Part #101-500) is a bare casting engineered for small block Chevy engine builds requiring high flow rates and precision intake geometry. This aluminum head features 2.02-inch intake and 1.60-inch exhaust valves paired with a 64cc combustion chamber, optimized for street performance and competition applications where cylinder head flow characteristics directly impact horsepower and torque output.

The 180cc intake runner volume is sized to support mid-range to high-RPM power delivery on small block Chevy platforms, balancing velocity for lower-RPM torque with adequate flow capacity at elevated engine speeds. The angle-plug configuration indicates spark plug positioning optimized for flame front propagation in modern combustion chamber designs. As a bare casting, this head ships without valve train components, allowing builders to specify their own valve springs, pushrods, rocker arms, and ancillary hardware to match their intended engine displacement, fuel delivery system, and target RPM range. Aluminum construction provides weight savings compared to cast iron alternatives while maintaining thermal conductivity for heat dissipation during sustained operation.

This cylinder head suits engine builders and enthusiasts developing small block Chevy platforms for street driving, drag racing, or road course use. Buyers should verify port matching with their selected intake manifold, confirm valve stem diameter compatibility (0.3410-inch standard for small block Chevy), and plan for professional machine work including valve seat installation, guide honing, and chamber finishing. Proper deck surfacing and gasket surface preparation are critical for sealing integrity and combustion efficiency.

Small block Chevy cylinder heads are categorized by intake runner volume and chamber size; the 180cc/64cc combination sits in the performance-oriented range suited for engines making 350+ horsepower. Buyers comparing cylinder head options should evaluate flow bench data, port shape, valve angle, and bolt pattern compatibility with their block and manifold selections before purchase.
