Fully CNC'd Intake / Exhaust Ports and Combustion Chambers!

The Edelbrock Victor Jr. LT1 cylinder heads are ideal for use in high performance street and competition engines that have reached their limit with a stock-style cylinder head design. Edelbrock's Victor Jr. LT1 cylinder heads are an all-new ground up design that incorporates subtle changes for improved flow and combustion. These changes were made to improve the limitations encountered in the stock cylinder heads when increasing the performance level of the engine. Changes include exhaust ports that have been moved 1.5" horizontally for improved air flow and will require custom headers. Also, 2.20" diameter intake valves with a canted configuration similar to what is utilized in the GM LT1 Gen V engine. These cylinder heads also feature fully CNC'd intake ports, combustion chambers and exhaust ports for consistency and improved performance. All of these changes make these cylinder heads capable of producing 750+ hp on an LT engine with stock rocker arms. Made In The USA!
