Description
These Big Chief cylinder heads from Dart 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. That's some serious performance, right out of the box!
