Dart Big Chief cylinder heads are the most powerful big-block heads you can buy! These heads put Pro Stock 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 valvetrain 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. With our sophisticated CNC machining programs, we can tailor a pair of Big Chief heads to fit your exact engine combination.

We have everything you need to build a complete Big Chief engine, including intake manifolds, valve covers, gaskets, and valvetrain components.
If you’re serious about winning, run with the Big Chiefs - or stay on the trailer!
