Trick Flow Twisted Wedge 11R Street 190cc Cylinder Head, SBF, 66cc Chambers

SKU: TFS-52516601-C01

Something great just got better! 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. You can get your Twisted Wedge® 11R 190 heads in two flavors:

* 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.

* 11R 190 heads with CNC Competition Ported high velocity, race-inspired runners feature fully CNC-machined runners and chambers, with a premium high-resolution finish for ultimate performance.

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.
