Edelbrock Victor 12-Degree CNC LS7 6-Bolt Cylinder Heads

Edelbrock Victor CNC 12-degree 6-bolt LS7 cylinder heads are specifically designed for maximum effort naturally aspirated and boosted applications. They feature .220 in. raised intake runners and .100 in. raised exhaust ports that provide a better line of sight into the cylinders and allow for an improved short turn. The raised intake runner design fits both stock and aftermarket LS7 intake manifolds and can be used with stock or aftermarket valvetrains. The heads utilize the GM LS 6-bolt design, making them 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 improves head gasket sealing, making them ideal for high-compression, naturally aspirated engines and high-boost applications.

Edelbrock Victor CNC cylinder heads feature a 12-degree valve angle and fully CNC-machined ports for maximum airflow. CNC-machined runners and chambers, as well as the .220 in. raised intake ports and the valve angle, increase overall flow capability, while a revised water jacket design enhances thermal conductivity and tunability. The 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 .400 in. raised valve cover rail make these heads ideal for maximum horsepower and high valve lift applications.

All Edelbrock Victor CNC heads feature patented Clean Cast Technology, a process that eliminates casting flaws and promotes a smoother internal surface finish for greater air and coolant flow. These benefits provide more power and increased cooling ability.
