Trick Flow Twisted Wedge Street/Strip Cylinder Heads for Ford 4.6L/5.4L 2V Tested and Ready!
The new modular heads are to be ready in April says Trick Flow. Read the blog for all the details.
Twenty years ago, Trick Flow Specialties revolutionized late-model Mustang performance with the introduction of the legendary High Port® cylinder heads, and did it again in 1996 with the release of the innovative Twisted Wedge® heads. In 2009, Trick Flow will revolutionize the Mustang scene once more with the debut of its newest high performance heads—the Twisted Wedge Street/Strip Cylinder Heads for Ford 4.6L/5.4L 2V engines!
The heads feature Trick Flow’s patented Twisted Wedge combustion chamber design coupled with an intake valve moved to the opposite side of the camshaft—just like the 3V heads on 2005 and later 4.6L/5.4L engines. The benefit is a dramatic increase in mid-lift airflow, plus increased piston-to-valve and valve-to-bore clearance that allows the use of higher lift cams and larger diameter valves without having to alter the bore size or flycutting the pistons.
Other important features include OE PI (Performance Improved) style intake inlets, Trick Flow’s patented Fast As Cast™ intake/exhaust ports that deliver near CNC-ported airflow out of the box, fully CNC-profiled combustion chambers, bulletproof 3/4" thick decks, four-bolt replaceable cam bearing journals, full 3/4"-reach spark plugs (no more blow outs or inserts!), stainless steel 1.840"/1.450" valves, Trick-Alloy powdered metal valve guides, ductile iron valve seats, lightweight chromemoly retainers and locks, die-forged locks, dual valve springs good for cams up to .600" lift, and Viton® fluoroelastomer valve seals.
The Twisted Wedge Street/Strip heads fit all 1996-2004 4.6L/5.4L 2V Romeo and Windsor engines (no modification of the oil passages in the block required) and all OE-type 2V camshafts, followers, lash adjusters, and valve covers bolt right on. Furthermore, 8mm end holes in the heads ensure that most OE Ford front covers will fit, too.
Twisted Wedge Street/Strip heads for PI engines have 38cc combustion chambers and deliver approximately 10:1 compression on a stock short block. Heads for non-PI short blocks have 44cc combustion chambers and also deliver about 10:1 compression. Bare cylinder head castings are also available.
