COMP Cams Valve Lash Caps 621-16

Trick Flow® 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.

Certain Twisted Wedge® 170 heads are emissions-legal under CARB E.O. #D-747-1 for 1996 and earlier Ford 289, 302,
and 351W engines. The heads are available fully assembled or as bare castings. Sold individually.
