Summit Racing™ Pro SBC LS Firing Order Hydraulic Roller Camshafts SUM-1223

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 190 head.

These heads are a direct replacement 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 provides 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.

Trick Flow® Twisted Wedge® 11R 190 cylinder heads are available fully assembled or as bare castings and sold individually.
