The Edelbrock part #77419 Victor 24 Deg 340cc cylinder head features a rolled over deck, altered valve locations and partially CNC’d 199cc chambers for cost effective performance. The Edelbrock 77419 cylinder head comes bare and will need a final valve job and guide sizing before use. 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″.
Edelbrock #77419 Victor 24 Degree is a bare cylinder head designed for Big Block Chevy 396-502 V8 engines. The Victor 24 Deg features a rolled over deck, altered valve locations and partially CNC’d chambers for cost effective performance.

Edelbrock introduces its new Big Vic CNC 12-degree race head, specifically designed for maximum competition naturally aspirated, nitrous injected, and boosted applications. The Big Vic 12 is cast in the USA at Edelbrock’s state-of-the-art foundry, using a premium aluminum alloy that undergoes hot isostatic pressing for a more stable and dense grain structure. The large CNC oval ports and 2.500 x 1.800 valve job are specifically designed to maintain high airspeed for maximum cylinder fill during valve opening and generate a high torque curve throughout the engine’s operating range. Manufactured with premium materials and machined to the industry’s tightest tolerances, these heads feature a 12-degree valve angle, copper valve seats, and fully CNC-machined 498cc ports and 82cc chambers to increase overall airflow capability. The premium manganese bronze valve guides withstand long wear with emphasis placed on holding precise tolerances on valve seat concentricity, allowing the valves to seal securely to eliminate leak-down and increase cylinder pressures during engine operation.
Edelbrock’s Big Victor cylinder heads are made with premium HIP aluminum alloy. They feature 498cc raised intake ports, 82cc chambers, and 2.500″ / 1.800″ Ex valve job.

Cylinder Head Specifications: Combustion chamber volume: 92cc; Intake runner volume: 442 (lh) / 451 (rh); Exhaust runner volume: 189cc; Intake valve diameter: 2.45″ (Valves Not Included); Exhaust valve diameter: 1.85″ (Valves Not Included); Valve stem diameter: N/A; Valve guides: Manganese bronze; Deck thickness: N/A; Valve spring diameter: Pocket diameter 1.76″ (springs not included); Valve spring maximum lift: N/A; Rocker stud: Use Jesel KPS-381754 shaft-mount; Guideplate: N/A; Pushrod diameter: N/A; Valve angle: 18° x 4.0° intake; 9° x 3.9° exhaust; Exhaust port location: N/A; Spark plug fitment: 14mm x 3/4 reach, gasket seat. * Intended for high output, large cubic inch racing engines with 4.84″ bore spacing, this head is an improvement over existing 18° designs, such as the Big Chief & Big Duke. The casting is made from A-356 aluminum and is Hot Isostatic Pressing processed (HIP) for superior strength, durability, dimensional stability and exceptional finish quality. These cylinder heads feature CNC ported intake ports and a raised exhaust runner design for improved flow efficiency. Chambers are fully CNC ported and extra material is included in the deck to allow fine tuning of the combustion chamber design, if desired. Edelbrock and Pat Musi worked with Jesel to improve the valvetrain geometry, delivering Pro-Stock level technology on engines up to 10,000 rpm. Jesel’s shaft-mounted system, #KPS-387154, is made from lightweight 7000 series aluminum and features a one-piece stand design that pairs the intake and exhaust stands for improved valvetrain stability. The intake features a 1.820″ long fulcrum and is available in 1.60:1 – 1.95:1 rocker ratios; the exhaust features a 2.000″ long fulcrum and available in 1.60:1 – 2.00:1 rocker ratios. Requires Edelbrock valve covers #4259. Match with Edelbrock Victor CNC Series manifolds #28003 and #28005. Pro-Port version available for custom porting.
