Edelbrock Victor CNC 11 6-Bolt Cylinder Heads for GM LS3 engines utilize the popular LS 6-bolt designmaking them compatible with the GM LSX block and all aftermarket iron or aluminum 6-bolt per cylinder LS race blocks. The 6-bolt design offers increased clamping capacity over the standard factory 4-bolt configuration and greatly improves head gasket sealingmaking them ideal for high compression naturally aspirated engines and high boost applications. These heads are manufactured with premium materials and machined to the industry’s tightest tolerances. Features include an 11 valve anglecopper infiltrated powder metal valve seats and fully CNC-machined ports for maximum airflow. The CNC-machined runners and chambersas well as the rolled 11 valve angleincrease overall flow capabilitywhile the revised water jacket design enhances thermal conductivity and tunability. The premium manganese bronze valve guides withstand long wear with emphasis placed on holding precision tolerances on valve seat concentricityallowing the valves to seal securelywhich eliminates leak down and increases cylinder pressure during engine operation. Finallythe .700 thick deck and reinforced rocker rails make these cylinder heads ideal for high horsepower applications. Edelbrock #77670 is a bare head.
