The Speedmaster PCE281.1355 is a Chevy SBC 350 cylinder head engineered for street and performance applications. Cast from aluminum with full CNC machining, this bare cylinder head features 217cc intake ports and a 64cc combustion chamber, providing a foundation for custom engine builds and rebuilds. The straight-port design and precision-machined specifications allow builders to optimize flow characteristics and compression ratios to match their specific engine combination and performance goals.
This bare head casting is ideal for engine builders, machine shops, and enthusiasts undertaking complete engine assembly or restoration projects. The full CNC machining ensures dimensional accuracy across critical flow paths and sealing surfaces. As a bare casting, it arrives without valves, springs, or gaskets, giving you full control over component selection and customization. Compatible with Chevy small-block (SBC) 350 engine platforms, the PCE281.1355 supports both street and performance-oriented builds where precision port geometry and chamber design are essential.
