What makes these cylinder heads different from stock LT4 heads?

These Edelbrock heads share the factory architecture but feature a thicker deck and port walls for added strength. They also have CNC machined combustion chambers and blended valve seats, along with gasket-matched intake and exhaust ports, to improve flow characteristics over stock.

Are these cylinder heads compatible with all LT4 engines?

These cylinder heads are specifically designed for the Gen V LT4 engine, identified by its 376 cubic inch or 6.2L displacement. Always verify your engine's specific model to ensure compatibility.

What is the benefit of CNC machining and gasket matching?

CNC machining ensures precise and consistent combustion chamber volumes and valve seat blending, which helps optimize airflow and combustion efficiency. Gasket matching the intake and exhaust ports smooths the transition between the head and the manifold or header, reducing turbulence and further improving flow.

Product Details

If you're looking to get more out of your Gen V LT4 engine, these Edelbrock Performer RPM cylinder heads are a solid choice. They're built with the same basic structure as the factory LT4 heads but feature some key updates that make a real difference. Edelbrock has beefed up the deck and port walls for extra strength, and they've CNC machined the combustion chambers and blended the valve seats. This means you get improved airflow right out of the box, which translates to better performance on the street.

What's really notable here is the attention to detail in the porting. The intake and exhaust ports are gasket-matched to help smooth the transition from your intake manifold and exhaust headers, further enhancing flow. While these are designed for street performance, the improved architecture and flow characteristics can make a significant difference in how your LT4 engine breathes and performs. They are built to be a direct replacement for your stock heads, simplifying the installation process.

Keep in mind that these heads are not CARB approved, so they cannot be shipped to California. If you're rebuilding the top end of your LT4 or looking for a way to unlock more power, these Edelbrock heads offer a well-built option with performance-focused enhancements.
