Dart Big Chief cylinder heads put technology within the reach of every racer and engine builder. They have what it takes to win today: spread intake ports, shallow valve angles, efficient combustion chambers, raised exhaust runners, and a valve train that's reliable at high-rpm. NEW 11° and 14° oval port designs raise the performance bar even further, with flow rates as high as 545 cfm. You can spend hundreds of hours and thousands of dollars modifying other castings to get the features that Big Chief heads give you an out-of-the-box package.
