The best standard port location cylinder head available for B/B Chevys, the Victor 24Á features a rolled over deck, altered valve locations and partially CNC'd chambers for cost effective performance. Starting with a A356 aluminum casting „ heat treated to T6 spec, they feature an extra thick deck and extra material in the spring pockets for heavy-duty casting that can be used with high-lift cam and heavy spring combinations. Edelbrock equips the complete heads with choice of spring packages to suite hydraulic or mechanical camshafts. Choose a hydraulic spring package for flat tappet or roller cams up to .700" lift. Mechanical cam spec heads include Manley dual-spring valve springs & titanium retainers good for up to .880" lift. The 340cc rectangle ports produce impressive flow and great power on competition big-blocks with 4.470" or larger bore. Exhaust port exits are raised .534" to greatly improve exhaust flow & power. #77439 is a great option for custom porting - seats and guides are included but not installed and the chambers are left unmachined.
