Notes: CYLINDER HEAD CYL HEAD BBC VICTOR JR 24 DEG CNC RECT PORT 300cc 118cc COMBUSTION CHAMBER FOR HYD ROLLER CAM
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.
