Description
Dart Pro 2 aluminum cylinder heads have been revised with larger 2.350 in. intake valves and a new port design for improved airflow and a substantial power increase. They're designed to make competitive engine building easier and less expensive by incorporating the rugged features of Dart's Race Series casting into ready-to-use, professional-quality cylinder heads. Every intake port, every exhaust runner, every valve bowl, and every combustion chamber is 100 percent digitally CNC-machined for the ultimate in consistency. These cylinder heads are available as bare castings or fully assembled. The fully assembled heads include stainless steel valves, valve springs, retainers, locks, and valve seals.
