SBF 190cc CNC Alm Cyl Head 60cc 2.020/1.550

The SBF 190cc CNC Alm Cyl Head 60cc 2.020/1.550 is a precision-engineered aluminum cylinder head designed for Small Block Ford engine builds requiring high-flow intake characteristics and proven reliability. Built for enthusiasts and professional engine builders who demand exact specifications and repeatable performance, this assembled cylinder head delivers the flow rates and chamber sizing necessary for both street and competition applications. Whether you're restoring a classic muscle car, building a hot rod, or optimizing an existing Small Block Ford platform, this CNC-machined component provides the foundation for increased horsepower and torque output.

This cylinder head features a 190 cubic centimeter intake runner volume optimized for mid-range torque and high-RPM air velocity, paired with a 60 cubic centimeter combustion chamber that balances compression efficiency with detonation resistance. The valve configuration specifies 2.020-inch intake and 1.550-inch exhaust valves, sized for maximum flow without sacrificing sealing integrity or longevity. The 1.460-inch valve springs provide appropriate seat pressure for reliable operation across extended RPM ranges, while the angle-plug design enhances flame front propagation and combustion efficiency. CNC machining ensures repeatability and tight tolerances, eliminating the variability inherent in traditional casting and hand-porting processes, critical for applications where consistency directly impacts engine durability and performance.

Builders targeting Small Block Ford platforms—including 289, 302, 347, and 408 displacements—will find this assembled cylinder head ready for valve train installation and final engine assembly. The pre-assembled design minimizes preparation time and reduces the risk of improper component orientation or valve spring installation error. Weighing 26.35 pounds, the head's aluminum construction reduces overall engine weight while maintaining the structural integrity required for sustained boost pressure or high-boost forced-induction applications. Proper installation requires attention to torque sequence, head gasket selection, and compatibility with your specific intake manifold and exhaust header configuration.
