Edelbrock Cylinder Head With CI PM Valve Seats Victor CNC 291CC 12-Degree Bare Finish

Edelbrock designed the 12-Degree 291CC Victor CNC Cylinder Head with CI PM Valve Seats for stock or aftermarket GM LS7 manifolds and a 6-bolt clamping capacity for GM LSX block, aftermarket iron or aluminum LS race blocks, and other naturally aspirated engines. The intake runner volume is 291cc and the combustion chamber volume is 69cc to support these booster power applications. Raised by 0.220 of an inch and 0.100 of an inch, the intake runner and exhaust ports enhance short turn into the cylinders thanks to the improved head gasket sealing and 12-degree valve angle for maximized airflow.

Features and Benefits:
- CNC Patented Clean Cast Technology™ Construction for Smooth Internal Surface Finish
- Raised Thick Deck, Valve Cover, Intake Runner, and Exhaust Ports for Added Cooling
