Trick Flow’s legendary Twisted Wedge® 170 series cylinder heads are better than ever! All of the unique features that made Twisted Wedge series heads so dominant in high performance and racing are still here—Twisted Wedge combustion chambers and valve layout, high-flow/high-velocity intake runners, and top-quality valvetrain components—plus CNC-profiled combustion chambers with port-to-valve seat blending (bowl blending) and refined Fast As Cast® runners that deliver near-CNC-ported power and airflow at cast head prices. The A356-T61 aluminum castings have been redesigned on the exhaust side to improve strength and water jacket integrity. Most Twisted Wedge 170 heads are 50 state emissions-legal under CARB E.O. number D-369-18 for 1996 and earlier Ford 289, 302, and 351W engines. Trick Flow Twisted Wedge 170 cylinder heads are available fully assembled or as bare castings.
