Trick Flow’s legendary Twisted Wedge® 170 series cylinder heads are better than ever! The A356-T61 aluminum castings have been redesigned on the exhaust side to improve strength and water jacket integrity for durability in street and entry level strip applications.
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.
Designed for hydraulic roller camshafts. Trick Flow twisted wedge pistons are required for use with these heads to allow for piston to valve clearance with camshafts over .550 in. lift. Valve cover rail is raised .350 in. over stock.
