Using proprietary Speed Flow technology, Dart has developed more efficient port designs with improved velocity and flow capabilities. The combustion chambers and ports have been redesigned for greater breathing characteristics and more controllable combustion. Casting walls are cleaner and more consistent, resulting in better control over flow and heat.

Features:

  • Standard 23 degree valve angle allows use of off the shelf pistons and valve train components.
  • Standard port location and intake bolt pattern fit most manifolds.
  • Pushrod holes are enlarged for clearance with high ratio rocker arms.
  • 5-axis CNC bowl blended for optimal flow characteristics.
  • Heart shaped chambers improve combustion efficiency and fit most standard pistons.
  • Multi-angle intake seats and radiused exhaust seats dramatically increase airflow.
  • Hardened exhaust seats are compatible with unleaded gasoline.
  • Manganese bronze intake valve guides and phosphorous bronze exhaust valve guides extend cylinder head life.
  • Spark plug holes are machined for tapered seat 5/8 hex peanut spark plugs.
  • Dual bolt pattern accepts flange mount and center bolt valve covers.
  • All cylinder heads sold individually.
