Something great just got better! Trick Flow used advanced 3D solid modeling and CAD tools (plus a couple decade's worth of racing experience) to turn its track-proven Twisted Wedge® design into the potent Twisted Wedge 11R 170 head.
Trick Flow Twisted Wedge 11R 170 heads are a direct replacement for previous Twisted Wedge heads and work with all Twisted Wedge-specific pistons. New high velocity, race-inspired CNC Street Ported runners have been optimized for today's popular bore and stroke combinations, and have a standard resolution surface finish for significant performance gains. Modified 11° intake and 13° exhaust valve angles and a restructured, CNC-profiled combustion chamber arrangement provides more airflow and performance potential.
Premium certified materials and components, along with the finest CNC tooling, are used to ensure exceptional quality and durability, dimensional accuracy, and balanced flow from port-to-port. The fully machined castings are very strong and have a great-looking, billet-like appearance.
Trick Flow Twisted Wedge 11R 170 cylinder heads are available fully assembled or as bare castings.
