Edelbrock BBC Big-Victor Pro Port 14 Degree HIP Cylinder Heads

Edelbrock and Pat Musi worked with Jesel to improve the valvetrain geometry, delivering Pro-Stock level technology on engines up to 10,000 rpm. Jesel's shaft-mounted system, #KPS-387154, is made from lightweight 7000 series aluminum and features a one-piece stand design that pairs the intake and exhaust stands for improved valvetrain stability. The intake features a 1.820" long fulcrum and is available in 1.60:1 - 1.95:1 rocker ratios; the exhaust features a 2.000" long fulcrum and available in 1.60:1 - 2.00:1 rocker ratios. Requires Edelbrock valve covers #4259. Match with Edelbrock Victor CNC Series manifolds #28003 and #28005. Pro-Port version available for custom porting.
