BBC PRO1 Heads |
| PRO 1 aluminum big-block cylinder heads deliver “out-of-the-box” airflow that beats the competition - at an unbeatable price! Inspired by our championship-winning Pro Stock designs, the PRO 1’s race-proven features include rolled valve angles, improved spark plug location, extra long intake valves, raised exhaust ports, and fast-burn chambers - yet the PRO 1 can be used with off-the shelf pistons, valvetrain components, and intake manifolds. |

BBC PRO1 CNC Heads |
| Dart PRO 1 CNC heads are professional quality competition cylinder heads. We applied the airflow technology developed in our championship winning Pro Stock engine program to produce these state-of-the-art heads. Every intake port, every exhaust runner, every valve bowl, and every combustion chamber is 100% CNC machined on special dedicated PRO 1 castings. Our five-axis computer controlled machining centers produce compound curves and complex shapes that no human could duplicate with a hand grinder. |

BBC Pro 2 Heads |
Dart's new CNC-machined PRO 2 aluminum cylinder heads with 380cc intake ports are just what the doctor ordered for large displacement big-block Chevrolet racing engines. With the growing popularity of Top Sportsman, Quick 32, and other go-fast classes, engine displacements have been steadily escalating. Dart's new 380cc PRO 2 heads have the airflow capacity to feed these massive motors.
Based on Dart's famous Race Series C355-T61 aluminum head casting, the new PRO 2 head's 380cc intake runners are paired with 144cc exhaust ports. Intake valves are 2.300 inches, and the exhausts measure 1.880 inches in diameter. Brass head bolt tubes are inserted between adjacent intake runners to allow the ports to be widened. |

BBC Race Series Heads |
| Dart developed the first successful aftermarket aluminum heads for big-blocks, and we’ve continued to improve and refine our revolutionary design. Dart big-block heads deliver superior performance without the hassles of welding and modifying stock castings. We applied proven Pro Stock technology to produce big-block heads that out perform the competition - yet Dart heads can be used with most off-the-shelf pistons, manifolds, headers, and valvetrain components. |

BBC Big Chief Heads |
| 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. They have since dominated in sportsman classes since their introduction, and we have continued to revise the design with the latest Pro Stock technology. With our sophisticated CNC machining programs, we can tailor a pair of Big Chief heads to fit your exact engine combination. |
