This Pro-Port Raw head is a semi-finished version of the Big-Victor spread-port designed for professional cylinder head porters. The casting is made from A-356 aluminum and is Hot Isostatic Pressing (HIP) processed for superior strength and durability, and exceptional finish quality.

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, #KPS-381754, 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 10,000 rpm. The intake features 7.820" long fulcrum available in 1.60:1 - 1.95:1 rocker ratios; the exhaust features 2.000" long fulcrum and 1.60:1 - 2.00:1 rocker ratios. Guides and seats are included but not installed. Requires Edelbrock valve covers 350-4259.
