Trick Flow Twisted Wedge 205 11R Competition Ported Cylinder Heads - FREE SHIPPING

Trick Flow® used advanced 3-D solid modeling and CAD tools (plus a couple decades' worth of racing experience) to turn its track-proven Twisted Wedge® design into the potent Twisted Wedge® 11R 205 head for serious performance enthusiasts and racers.

Trick Flow® Twisted Wedge® 11R 205 heads are direct replacements for previous Twisted Wedge® heads and work with all Twisted Wedge®-specific pistons. New high-velocity, race-inspired CNC Competition Ported runners have been optimized for today's popular bore and stroke combinations, and have a premium high-resolution finish for ultimate performance. Modified 11 degree intake and 13 degree exhaust valve angles and a restructured, CNC-profiled combustion chamber arrangement provide more airflow and performance potential.

Premium certified materials and components, along with the finest CNC tooling, are used to ensure uncompromising 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.
