The Speedmaster PCE281.1260 is a fully machined, bare aluminum cylinder head designed for small-block Chevy (SBC) 350 engines. Featuring a 217cc intake port volume and 70cc chamber, this head is engineered with full CNC precision to deliver consistent flow characteristics and reliable performance. The angle configuration optimizes port alignment for improved combustion efficiency and power delivery across the RPM range.
This bare aluminum casting provides builders with a clean, quality foundation for high-performance engine assembly. The CNC-ported design ensures repeatability and precision that hand-ported alternatives cannot match, making it ideal for street, strip, and competition applications. As a bare head, it arrives ready for final assembly with your chosen components, allowing maximum flexibility in engine building and customization.
