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.

- Standard port location and intake bolt pattern fit most manifolds
- Pushrod holes enlarged for clearance with high ratio rocker arms
- Heart shaped chambers improve combustion efficiency
- Multi-angle intake seats and radiused exhaust seats dramatically increase airflow
- Hardened exhaust seats 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
