GM LS 276cc CNC ALUMIN HEADS BARE 70cc, 2.165″/1.60″ 6 BOLT

Description

Maximizing engine output starts with optimizing airflow and combustion efficiency. These GM LS 276 cc CNC aluminum heads offer precision engineering that directly boosts performance for high-demand applications.

The 276 cc intake port volume is meticulously CNC-machined to ensure consistent, high-velocity airflow, which enhances volumetric efficiency and power delivery across the RPM range. The 70 cc combustion chambers promote higher compression ratios, improving combustion and thermal efficiency for increased horsepower and torque.

Valve sizes of 2.165 inches intake and 1.60 inches exhaust provide a balanced approach to airflow capacity and valve train durability. The larger intake valves facilitate greater air intake, while the exhaust valves optimize gas expulsion, reducing backpressure and enhancing throttle response.

• CNC-machined aluminum construction reduces weight to 20.5 kg, easing overall engine mass and improving vehicle handling dynamics.
• Compact dimensions (52 cm length, 30 cm width, 24 cm height) ensure compatibility with a wide range of LS engine configurations without requiring extensive clearance modifications.
• Robust 6-bolt design enhances cylinder head stability under high boost or high-performance conditions, minimizing gasket failure risk.
• Bare heads provide a versatile platform for customization, allowing builders to tailor valve springs, retainers, and other components to specific performance goals.

Manufactured by Aeroflow, a brand known for precision and durability in engine components, these heads are engineered to meet the rigorous demands of professional builds and serious enthusiasts alike.
