Since then, the -12 cylinder head has won thousands of late model and sprint car races and is still winning races today. BRODIX has taken this design even further by adding raised intake ports, several valve spacings, and more efficient combustion chambers. The -12 cylinder head is available in several port sizes to fulfill our customers’ needs.
