BBC 290cc Alm Cylinder Head Assembled

The FLOTEK BBC 290cc Aluminum Cylinder Head Assembled is a fully prepared big-block Chevy engine component engineered for builders and engine shops requiring a ready-to-install head assembly. This aluminum casting combines a 290cc intake port volume with a 112cc combustion chamber, delivering the flow characteristics and thermal properties demanded by both street and performance engine builds. The assembly arrives with valve springs, angle-plug configuration, and precision-finished valve seats, eliminating the need for secondary machine work on most installations.

The 2.300-inch intake and 1.880-inch exhaust valve diameters optimize the flow path from intake manifold to combustion chamber while maintaining structural integrity in the valve pocket area. The 1.530-inch valve spring specification is sized to manage typical street and mild performance cams without sacrificing reliability. Aluminum construction reduces overall engine weight compared to cast-iron alternatives, a consideration across applications from marine power plants to high-performance vehicles where mass distribution affects handling and efficiency. The angle-plug design positions the spark plug for improved ignition characteristics and easier access in tight engine bay configurations.

This cylinder head suits engine builders, machine shops, and enthusiasts building or refreshing big-block Chevy powerplants where a complete, ready-to-bolt head assembly saves assembly time and reduces the risk of missed specifications. The pre-assembled valve train means no separate sourcing of springs, keepers, or related fasteners. Part number 290-600 is the industry reference for this configuration, ensuring compatibility with core engine packages, intake manifolds, and exhaust systems engineered around the BBC platform.
