Iron Eagle Pro SBC 227 Cylinder Head
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 23 degree valve angle allows use of off the shelf
pistons and valve train components.
- Standard port location and intake bolt pattern fit most
- Pushrod holes are enlarged for clearance with high ratio rocker
- 5-axis CNC bowl blended for optimal flow
- 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
