Description

Enhance your Big Block Chevy engine's performance with the FLOTEK BBC 290cc Aluminum Cylinder Head. Designed for moderate street or street/strip applications, this assembled cylinder head features 290cc intake runners and 112cc combustion chambers, optimizing airflow and combustion efficiency. Equipped with 2.300-inch intake and 1.880-inch exhaust valves, along with dual valve springs supporting up to 0.750-inch lift, it ensures durability and high performance. The heart-shaped combustion chamber design may require piston clearance checks with certain domed aftermarket pistons. FLOTEK recommends modifying the piston rather than the cylinder head to maintain optimal flow and power performance. Ideal for engines up to 509 cubic inches operating at or below 6,500 RPM.

Disclaimer

Ensure proper piston to head clearance before installation. Modifications may be necessary for certain domed aftermarket pistons. FLOTEK recommends modifying the piston rather than the cylinder head to maintain optimal performance.
