Notes:
Designed for use with hydraulic roller camshafts. Valve cover rails are raised .350" above stock height. These cylinder heads are compatible with stock pistons when used with Trick Flow Track Max® Hydraulic Roller Camshafts TFS-51503001 and TFS-51503002. The heads are typically compatible with stock pistons and other aftermarket camshafts up to approximately .550" valve lift, depending on the camshaft specifications and timing. It is highly recommended to verify proper piston-to-valve clearance with all aftermarket camshafts before operating the engine.
Trick Flow® Twisted Wedge® Track Heat® 170 Cylinder Heads for Small Block Ford
Trick Flow’s legendary Twisted Wedge 170 series cylinder heads are back and better than ever! The updated A356-T61 machined castings are borrowed from Trick Flow’s 11R series head lineup, bringing with it increased strength thanks to a .625" thick deck and a great-looking, billet-like appearance.
The groundbreaking Twisted Wedge combustion chamber moves the intake valves away from the cylinder walls to reduce valve shrouding and significantly enhance high-lift flow. Altered 15° intake/17° exhaust valve angles tighten the combustion chamber to increase compression while improving piston-to-valve clearance. That allows the use of higher lift cams with stock pistons. CNC-profiled combustion chambers with relocated spark plug locations optimize combustion efficiency, extracting more power with less ignition timing and reducing the potential for detonation.
The choice of 58cc or 61cc combustion chamber volumes allow builders to dial-in the perfect compression ratio. High-efficiency, Fast As Cast® runners feature a competition level, multi-angle valve job for near-CNC-ported power and airflow at cast head prices.
Assembled Twisted Wedge 170 cylinder heads arrive ready-to-run out of the box with top-quality valvetrain components to ensure great durability and longevity. This includes stainless steel valves, bronze guides, PAC Racing valve springs, thread-in 3/8" or 7/16" rocker studs, and chromoly retainers. Some Twisted Wedge 170 cylinder heads are emissions-legal under CARB E.O. #D-747-1 for 1996 and earlier Ford 289, 302, and 351W engines.
Cylinder heads are available fully assembled or as bare castings. Sold individually.
