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.

These heads exceeded my expectation for sure! First was the fact they have the upgraded valve springs, dual springs at that! Also they have the 10 degree valve locks which some believe are a wee bit stronger than the typical 7 degree ones. FYI: If you buy these heads for your SBF and use 7/16" head bolts you do NOT need the special head bolt bushings. The head bolt holes are designed to use the 7/16" bolts but if you do have the 1/2" bolts, it would be very easy to drill out the the holes to fit the larger bolts. I gave the heads a 4 star because of the fact as of 6/28/2014, Trick Flow did not have the exact manual for these heads. For some unknown reason they used a manual for another head #TFS-5141002-M58 in its place. ...read more
