Edelbrock part #61409 Victor 24 Degree CNC rectangular port cylinder heads are designed for use with large cubic inch and/or high air demand Big Block Chevy engines with a minimum 4.47" diameter bore.
Edelbrock and Pat Musi Performance have combined efforts to produce the finest standard intake port location big-block Chevy head available. The Edelbrock #61409 Victor 24deg CNC cylinder head features 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 cylinder head with Manley dual-spring valve springs and titanium retainers good for up to .880" lift. The port designs are large oval (367 lh / 377 rh) that produce impressive flow - out-of-the-box. The exhaust port exits are raised .750" to greatly improve exhaust flow and power. Off the shelf large oval-port intakes are available through Edelbrock.
