If you feel like you have reached the limit with a stock-style cylinder head, Edelbrock has developed the Victor Jr. LS3 cylinder head. These are ideal for performance street and competition engines. This head features an all new design that increases flow and combustion. Changes include an intake valve with a canted configuration similar to what is utilized in the GM LT1 Gen V engine. The intake valve change along with the unique port shape produce almost 400cfm peak flow. These cylinder heads also feature fully CNC intake ports, combustion chambers and exhaust ports for consistency and improved performance. All of these changes make these cylinder heads capable of producing 600+ hp on an LS3 engine with stock rocker arms, intake manifold and exhaust manifolds. This cylinder head features a 4-bolt flange.
