Notes: Cylinder Head Victor Jr. Aluminium Bare 118cc Chamber 300cc Intake Runner Chevrolet Big Block
These heads feature an extra thick deck and extra material in the spring pockets for a heavy-duty casting that can be used with high-lift cam and heavy spring combinations. Edelbrock equips the complete heads with your choice of spring packages to suit hydraulic or mechanical roller cams. Choose a hydraulic spring package for flat tappet or hydraulic roller cams up to .700 lift. Mechanical roller cam spec heads include Manley dual-spring valve springs and titanium retainers good for up to .880 lift. The 300cc rectangle ports produce impressive flow and great power on competition big-blocks up to 510 c.i.d. with 4.310 or larger bore. Exhaust port exits are raised .534 to greatly improve exhaust flow and power.
