Edelbrock VICTOR CNC 11° 6-BOLT Cylinder Heads [PORT VOLUME 263cc | CHAMBER 68cc | SPARK PLUGS Angle | VALVE SIZE IN. 2.165" EX. 1.600" | VALVE SEAT PM | VALVE TRAIN Bare] (GM 6.2L LS3)

The EDELBROCK VICTOR CNC 11° Cylinder Heads for GM LS3 engines utilize the popular LS 6-bolt design, making them compatible with GM LSX blocks 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 sealing, ideal for high-compression naturally aspirated engines and high-boost applications.
