The big Victor 12 Degrees and 14 Degrees designs offer improved air flow and power compared to existing 18 Degrees designs. Making an already proven casting and design even better then before. Both of these cylinder heads also include the same redesigned valvetrain geometry for improved stability, delivering Pro-Stock level technology on engines up to 10000 RPM. Requires the use of a jesel or tandd shaft-mounted rocker system. Requires Edelbrock valve covers or other options manufactured by Moroso. Compatible with most 11 Degrees, 12 Degrees and 14 Degrees big chief style pistons. Match with Edelbrock big Victor and big Victor 2 spread port intake manifolds for the ultimate big block Chevy spread port combinations. Big Victor 18 Degrees heads are compatible with most 18 Degrees big chief style pistons. Edelbrock and pat Musi worked with jesel to develop a new shaft mounted rocker system designed specifically for these heads that greatly improves valvetrain geometry. Jesel's shaft mounted system features a one piece stand design with paired intake and exhaust stands for valvetrain stability. This is the same technology used on Pro-Stock race engines, providing stability up to 10000 RPM. The intake features 1.820 Inch Long fulcrum available in 1.60:1 to 1.95:1 rocker ratios, the exhaust features 2 Inch Long fulcrum and 1.60:1 to 2.00:1 rocker ratios. Guides and seats are included but not installed
