GM LS 276cc CNC ALUMIN HEADS BARE 70cc, 2.165″/1.60″ 4 BOLT

Description

Enhance your engine’s power output and reliability with CNC-machined aluminum cylinder heads engineered for precision and durability. These heads solve airflow limitations common in stock components, enabling your engine to breathe more efficiently and produce higher horsepower.

Crafted from lightweight yet robust aluminum, these heads reduce overall weight to 20.5 kilograms, improving vehicle balance and handling. The 276 cc intake runners are optimized to maximize air volume flow, allowing for greater combustion efficiency and improved throttle response.

• 70 cc combustion chamber: Smaller chamber size increases compression ratio potential, resulting in improved power and fuel efficiency.
• 2.165″ intake and 1.60″ exhaust valves: Oversized valves improve airflow dynamics, enhancing volumetric efficiency and engine breathing at high RPMs.
• Four-bolt design: Ensures secure mounting and maintains head gasket sealing under high-performance conditions.
• Dimensions (52 cm L x 30 cm W x 24 cm H): Compatible with most GM LS engine blocks, facilitating straightforward installation without extensive modifications.
• Precision CNC machining: Guarantees exact tolerances for optimal sealing surfaces and consistent performance across all units.

These cylinder heads are engineered specifically for GM LS engines, providing a direct upgrade path for racers and performance enthusiasts seeking measurable gains in power and reliability. The combination of advanced airflow design, durable materials, and precise manufacturing makes these heads an indispensable component for any serious engine build.

Invest in these CNC aluminum heads to unlock your engine’s full potential with components built to exacting standards and engineered to deliver consistent, high-performance results.
