Trick Flow’s new Twisted Wedge 11R cylinder heads feature 11° intake and 13° exhaust valve angles and a restructured combustion chamber arrangement for more airflow and performance potential. The new high velocity, race-inspired runners have been optimized for today’s popular bore and stroke combinations.
Twisted Wedge 11R 170 and 190 heads with CNC Street Ported runners are great entry-level CNC heads combining fully CNC-machined runners and combustion chambers with a standard resolution surface finish for significant performance gains.
Twisted Wedge 11R heads are for use on non-emissions engines, but these cylinder heads will accept factory emissions (AIR Injection) and are street ported. The heads are a direct replacement for previous Twisted Wedge heads and work with all Twisted Wedge specific pistons.

Trick Flow - Serious Horsepower
Horsepower doesn't happen by accident. It takes time, skill, and the right combination of parts to allow your engine to produce optimum power levels.
Trick Flow engineers use advanced Computer-Aided Design (CAD) work stations and high-tech 3D modeling to develop and analyze components quickly and accurately. Trick Flow machinists use state-of-the-art rapid physical prototyping, CNC-machining centers, and hot rodding know-how to turn designs into molds and foundry tooling.
Prototypes and products are subjected to hours of relentless testing on one of Trick Flow's dynamometers, and extensive road and race track data is gathered to guarantee parts perform as intended. Trick Flow's commitment to quality combined with a "zero defects" attitude ensures Trick Flow products will exceed your expectations.
From Lightning cylinder heads to Mustang camshafts, pistons to intake manifolds, Trick Flow is committed to making products that are designed and engineered to deliver power!
I have been restoring my car for a long time. The engine is a 331 stroker afr 185 heads, trick flow r series intake, 1 3/4 in long tubes with flow master dumps. Sounds awesome and love it every ride. ...
