52616601-C03 Trick Flow Twisted Wedge 11r, 205 CNC Cylinder Heads, 66cc Chamber, Pair

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 205 head for serious performance enthusiasts and racers. Trick Flow Twisted Wedge 11R 205 heads are a direct replacement 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° 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 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.

Uses 7/16" stud mount roller rocker arms.  Cylinder heads are drilled for 1/2" head bolts, if using 7/16" head bolts bushing are required.  Includes guideplates for 5/16" pushrods.
