Edelbrock Victor 11-Degree CNC LS3 6-Bolt Cylinder Heads

Edelbrock Victor CNC 11-degree 6-bolt LS3 cylinder heads are specifically designed for high-horsepower, naturally aspirated, and boosted applications. Utilizing the popular LS 6-bolt design, they are compatible with the GM LSX block and all aftermarket iron or aluminum 6-bolt per cylinder LS race blocks. The design offers increased clamping capacity over the standard factory 4-bolt configuration and greatly improves head gasket sealing, making them ideal for high-compression naturally aspirated engines and high-boost applications. Edelbrock Victor CNC heads are manufactured with premium materials and machined to the industry's tightest tolerances. They have an 11-degree valve angle, copper infiltrated powder metal valve seats, and fully CNC-machined ports for maximum airflow. The machined runners and chambers, along with the valve angle increase overall flow capability, while the revised water jacket design enhances thermal conductivity and tunability. Premium manganese bronze valve guides withstand long wear with emphasis placed on holding precision tolerances on valve seat concentricity, allowing the valves to seal securely, eliminating leak down and increasing cylinder pressure during engine operation. Finally, the .700 in. thick deck and reinforced rocker rails make these cylinder heads ideal for high-horsepower applications. Show Less
