Looking for serious small block Ford horsepower?
Trick Flow® Twisted Wedge® Street heads are 50-state emissions-legal for 1996 and earlier 289, 302, and 351W Fords (CARB E.O. number D-369-1)! Twisted Wedge® heads feature an exclusive combustion chamber design. The patented 61cc chambers feature rotated intake and exhaust valves moved over the center of the cylinder bores. As a result of optimizing the valve locations, valve angles, and combustion chamber shape, the Twisted Wedge® heads use stock height exhaust ports without power loss. The heads are machined for 2.020 in. intake/1.600 in. exhaust valves to build top-end power without sacrificing bottom-end torque. They don't require flycut pistons for use with cams up to the specifications listed--no other 2.020 in.-valved head for small block Ford offers these features! The Twisted Wedge® Street heads are built for heavy-duty use, too. They have .560 in. thick combustion chamber walls and a fire deck for strength without compromising cooling capacity. Additional support risers are strategically located in the water jacket for additional rigidity and head gasket integrity. Twisted Wedge® Street heads have stock height intake and exhaust ports that allow for the use of most OEM and aftermarket intake and exhaust manifolds. Fully assembled heads come with stainless steel valves (intakes are backcut for improved flow), valve springs, locks, retainers, rocker studs, and guideplates. The heads are also available as bare castings.
