Show original supplier description

The Trick Flow® Twisted Wedge® 11R 170 Cylinder Heads represent an evolution of Trick Flow's track-proven Twisted Wedge® design, optimized for modern small block Ford engines. Utilizing advanced 3D solid modeling and CAD tools, these heads offer enhanced performance potential compared to previous iterations. These assembled aluminum cylinder heads feature 170cc CNC-ported intake runners and 66cc exhaust runners, with a 53cc combustion chamber volume. The intake ports are rectangular, and the exhaust ports are square, with standard port locations. The unique Twisted Wedge® combustion chamber design, combined with modified 11-degree intake and 13-degree exhaust valve angles, promotes improved airflow and performance. The heads are CNC-machined for dimensional accuracy and balanced flow, featuring a standard resolution surface finish on the runners. Included with these heads are 2.020-inch intake valves and 1.600-inch exhaust valves, dual valve springs capable of handling up to 0.600-inch lift, chromoly steel retainers, 7-degree locks, and bronze valve guides. They are set up for hydraulic roller camshafts and feature 3-angle valve seats made from ductile iron. The notes indicate that for blocks machined for 7/16 in. head bolts, the use of TFS-51400419 head bolt bushings is required. These are non-emissions, street-ported heads sold individually.
