TFS Twisted Wedge 11R 227 Cylinder Heads - (56cc)
Twisted Wedge 11R 227 cylinder heads represent Trick Flow's ultimate development of the Twisted Wedge innovation, featuring Trick Flow's most efficient combustion chamber design. The combustion chamber and valve layout move the intake valves away from the cylinder walls to reduce valve shrouding, significantly improving flow at higher lift.
Shallow 11° intake/13° exhaust valve angles improve piston-to-valve clearance for high lift cams and reduce chamber volume for improved compression and efficiency. High velocity runners are optimized on the flow bench and dyno proven to outperform the competition on hydraulic roller camshaft engines.
Premium materials and components, along with world-class CNC processes, guarantee uncompromising quality and durability, dimensional accuracy and balanced flow from port-to-port.
Machined castings increase strength and have a billet-like appearance. Additional features include CNC-profiled combustion chambers, 2.080"/1.600" stainless steel intake/exhaust valves, Trick Flow by PAC Racing valve springs and titanium retainers.
Twisted Wedge 11R 227 heads have CNC Competition Ported runners with a premium high- resolution finish for ultimate performance.
