This head was specifically designed and developed for Tony Stewart’s World of Outlaws Sprint Car Programs. Featuring a rocker pad designed by MBE. This is the only head in the industry capable of over 200 RPM’s. This design is proven to be far more stable for the valve train, increasing the valve and lifter life.
