Dart Big Chief CNC Aluminum Big Block Chevy Cylinder Heads

For 5.000 in. bore space engines. Maximum Top Sportsman, Top Dragster, Pro Mod and Pro Street competition. Excellent with alcohol and nitrous, over 7,000 RPM. The original Dart Big Chief put the spread port design on the map, winning three NHRA Pro Stock championships before being banned from the class. Our 14 Deg Big Chief’s have dominated in Sportsman classes since their introduction, and we have continued to improve the design with the latest Pro Stock technology now available in 5.000 in. bore centers. With our sophisticated CNC machining programs, we can tailor a pair of Big Chief heads to fit your exact engine combination.
