The FLOTEK SBC 200cc Aluminum Cylinder Head with 64cc combustion chamber is engineered for small-block Chevrolet engines seeking reliable performance gains and improved airflow characteristics. Built for enthusiasts and professional builders who demand quality castings without the premium price tag, this head delivers the flow characteristics necessary for mid-range and high-RPM builds. Whether you're upgrading a street engine or constructing a weekend warrior, this aluminum casting provides the foundation for measurable horsepower and torque improvements over factory iron heads.

Featuring 200cc intake runners and a 64cc combustion chamber, this head is optimized for engines in the 350–400 cubic inch displacement range, with intake and exhaust valve sizes of 2.055 inches and 1.600 inches respectively. The aluminum construction reduces overall engine weight while improving heat dissipation compared to traditional iron heads, critical for sustained performance and reliability under boost or aggressive naturally-aspirated conditions. The precision casting ensures proper valve seat concentricity and port matching, while the 64cc chamber volume supports compression ratios between 9.5:1 and 10.5:1 depending on piston selection, making this head versatile across various build configurations.

This cylinder head is ideal for builders upgrading factory SBC platforms, street/strip applications, or small-block swaps requiring quality castings without custom porting expenses. Weighing 27.7 lbs, it is a practical choice for those looking to enhance their engine's performance without adding unnecessary weight. The FLOTEK SBC 200cc Aluminum Cylinder Head is a reliable option for anyone looking to achieve significant performance improvements.
