SBF 180cc Alum Cyl Head 58cc 1.94/1.55 Bare

The SBF 180cc Alum Cyl Head 58cc 1.94/1.55 Bare is a precision aluminum cylinder head engineered for Small Block Ford engines seeking maximum flow capacity and reliability. Built for high-performance engine builders, restoration shops, and motorsports enthusiasts, this bare head provides the foundation for custom valve train configurations and optimized combustion chamber design. The 180 cubic centimeter intake volume and 58 cubic centimeter combustion chamber deliver the breathing characteristics needed for both street and competition applications where stock performance falls short.

Manufactured from cast aluminum alloy, this cylinder head features a bare casting with no valvetrain components installed, allowing builders complete control over valve selection and timing geometry. The 1.94-inch intake valve and 1.55-inch exhaust valve dimensions are optimized for SBF platforms, providing improved volumetric efficiency compared to stock alternatives. Angle-plug spark plug positioning enhances combustion efficiency and allows for more aggressive ignition timing curves. The bare design means zero compromise—every builder can port match, flow test, and assemble with their choice of premium valves, springs, keepers, and seals for maximum durability and performance.

This head is ideal for Small Block Ford engine rebuilds where OEM components have reached service limits or where displacement and power output increases are the objective. Professional machine shops and experienced rebuilders benefit most from the bare format, as it eliminates core exchange fees and inspection delays inherent in complete assemblies. Installation requires proper block surface preparation, torque sequence compliance, and quality gasket materials; most builds pair this head with matching intake manifolds and carburetors or fuel injection systems tuned to the increased airflow capacity. Weighing 20.7 pounds, it meets strict specifications for SBF compatibility without requiring block modifications.
