Twisted Wedge Cylinder Heads are great for extracting horsepower from your small block Ford! Trick Flow's cylinder head features 190cc intake runners, 2.055 intake valves, 1.60 exhaust valves, dual springs and 66cc combustion chambers. This head is the perfect addition to your 289, 302 or 351W engine.

Full CNC competition porting provides better flow, for more power! The 11R is a bolt-on performer with premium-grade materials and components. 11-degree intake and 13-degree exhaust valve angles set this head apart from the original Twisted Wedge heads. This configuration increases airflow for even more performance!

These are paired with a CNC-profiled combustion chamber for better airflow and performance potential. This head features high velocity, race-inspired CNC competition ported runners which offer better performance over the street ported runners.

Twisted Wedge series heads are known for their twisted wedge combustion chambers and valve layout, high-velocity intake runners, top quality valvetrain components and, in this case, complete CNC-profile. Smooth CNC machined intake and exhaust runners provide the best surface for increased airflow. This cylinder head comes fully assembled.
