    The Chevrolet Performance C5R/LSX/LS7 Racing Aluminum Cylinder Head is an unmachined "cubed" aluminum racing head designed for the professional engine or cylinder head builder. This allows a clean slate start to design the ultimate racing cylinder head for a 4.100" or larger bore LS-series racing engine. This cylinder head design has been validated in competition in the showroom stock C5R Corvette race car program, so be assured this head will live up to your demands!
