Chevrolet Performance 19419196 - LSX LS7 CNC Ported Bare Cylinder Head

These LSX LS7 heads are made from premium 356-T6 aluminum and feature a 0.625" thick deck for increased strength to meet the demands of high horsepower applications. Rocker supports and other areas in the LSX head have been reinforced with added material for superior structural integrity and to meet the demands of custom engine builders. The LSX LS7 CNC port is not the same port design as the stock GM LS7 port. This port has been developed for increased airflow while while using the stock GM 2.200" intake and 1.610" exhaust valve sizes. This new CNC port improves the intake flow over the stock LS7 by approximately 13%.
The LSX head can be used on both the factory stock blocks or the 6-Bolt design LSX block for increased clamping capacity.
