SBC CNC 18-Deg Cylinder Head 272cc Bare

The DART SBC CNC 18-degree cylinder head with 272cc chamber is designed for small-block Chevrolet builders focused on enhancing engine performance and reliability. This bare casting is ideal for custom engine builds where airflow efficiency and combustion geometry are crucial for maximizing horsepower and torque.

Utilizing DART's CNC porting process, this cylinder head optimizes intake and exhaust port geometry, resulting in improved airflow characteristics compared to stock options. The 272cc combustion chamber volume is engineered to provide proper quench and compression ratios when paired with standard bore SBC blocks, while the 18-degree valve angle enhances valve overlap and breathing efficiency during operation.

This head is particularly beneficial for builders of street machines, weekend racers, or restoration projects, allowing for precise tuning of valve train geometry and timing events. It is compatible with various small-block Chevrolet engines, including 262, 283, 302, 327, 350, and 400 cubic inches, and works well with both carbureted and fuel-injected systems.
