Chevy Twisted Wedge G2 Aluminum Head |
Trick Flow’s Twisted Wedge will produce 50 more horsepower than Corvette L98 aluminum heads on a 350 cubic inch small block. The key to making this horsepower is in the patented, rotated valves angles. This un-shrouds the intake valve and moves the spark plug closer to the center of the cylinder. This creates a more complete burn of the incoming air/fuel charge. The 190cc intake ports and 82cc exhaust ports are a high velocity design with small cross-section runners on the intake, providing both low-rpm torque and high rpm horsepower. They feature 67cc combustion chambers and are available in early or late model versions and your choice of valve springs. They come fully assembled with 2.02” and 1.60” one piece stainless steel valves, 1.470” valve springs, 7 degree machined keepers and retainers, guide-plates , rocker arm studs, and hardened head bolt washers. They accept most aftermarket performance rocker arms, factory intake manifolds, most brands of headers, and factory bolt-on accessories. They feature CARB E.O. number D-369-2 for use in California. Special length pushrods are needed. With standard pistons they will handle cams up to .490” lift and 236 degree @ .050” on 110 lobe separation. G2 forged pistons are available from Trick Flow and will handle up to .601” cam in non-emission applications. Price is per set.

Twisted Wedge and Track Heat Aluminum Head |
In dyno tests, a 5.0L Cobra engine equipped with Trick Flow’s Twisted Wedge heads, a GT-40 intake and E-303 cam made 328 horsepower and 354 ft/lbs of torque. That’s 78 more horsepower and 54 ft/lbs more torque than the stock Cobra engine and 10 horsepower and 2 ft/lbs more torque than the “old-style” Trick Flow high-port Ford heads. They feature high velocity 170cc intake ports, 66cc exhaust ports and 61cc combustion chambers. Patented rotated intake and exhaust valves are moved over towards the center of the bores. This unshrouds the valves and optimizes the valve locations, valve angles, and combustion chamber shape, while using stock intake and exhaust port locations. The .56” combustion chamber walls are designed for heavy duty use such as nitrous, blowers and turbos. The Twisted Wedge features 2.02” and 1.60” one piece stainless steel valves, 1.47” valve springs, 7 degree machined keepers and retainers, 3/8” rocker studs and guideplates. They will handle up to .540” with factory flat top pistons. These Trick Flow Twisted Wedge heads are 50-state emissions-legal for 1996 and earlier 289, 302, and 351W Fords. Carb E.O. D-369-1. The Track Heat heads feature upgraded valve springs, 10 degree super locks and retainers, and 7/16” rocker studs for cams up to .625” with Trick Flow forged pistons. Price is per set.
