Edelbrock Victor Jr. LS3 Aluminum Cylinder Head The Edelbrock Victor Jr. LS3 aluminum cylinder head is all-new ground-up design that incorporates subtle changes for improved air flow and combustion. The large 2.20" diameter intake valve with a canted configuration similar to the GM LT1 Gen V engine. The unique rectangular intake port design is fully CNC-machined to a 400 cfm peak flow. Fully CNC-machined heart-shaped combustion chambers, and round, raised exhaust ports for maximum performance. These heads are capable of producing 600+ hp on a LS3 engine using stock rocker arms, intake manifold, and exhaust manifolds. Sold each.

Edelbrock E-CNC LS3 Aluminum Heads The E-CNC LS3 aluminum cylinder heads are a great general-purpose high-perfor- mance head for any street-strip LS-based engine. These heads have a high-velocity port compare to the stock LS3 heads upgrade for any cathedral-port 3.890" bore LS application. Features include: CNC intake ports, raised (0.125") exhaust ports, .200" machined spring pockets for use of longer valves and rolled valve angle (13°) for improved combustion. Can be used with 4- and 6-bolt configurations. Compatible with stock rocker arms. Sold individually.

Trick Flow GenX LS Aluminum Cylinder Head Trick Flow GenX LS cathedral-port aluminum cylinder heads for GM LS1/LS2 engines are fully CNC-machined with altered valve angle from 15° to 13.5° to decrease the valve shrouding, increase mid-lift airflow, and improve rocker arm- to-valve cover clearance. Material was added at the rocker arm mounting points for increased stability. Relocated spark plugs in the CNC-profiled heart-shaped combustion chambers to enhance mid-lift airflow for extreme horsepower appli- cations.
