52516601-C01 Trick Flow Twisted Wedge 11r, 190cc CNC Cylinder Heads, 66cc Chamber, Pair

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 190 heads.

Trick Flow® Twisted Wedge® 11R 190 heads are direct replacements for previous Twisted Wedge® heads and work with all Twisted Wedge®-specific pistons. Modified 11 degree intake and 13 degree exhaust valve angles and a restructured, CNC-profiled combustion chamber arrangement provide more airflow and performance potential.  11R 190 heads with new high velocity, race-inspired 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.

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.

Note* The included TFS 11R Valve Springs will work with Anderson Camshafts (pt # TFS-16306-16)
