Trickflow Twisted Wedge 38cc Heads
Bolt-on Trick Flow's 185cc cylinder heads and add some serious power to your 1999-2004 SVT Lightning. The power comes from the patented Twisted Wedge 38cc combustion chamber design with the intake valve moved to the opposite side of the camshaft. The benefit is a dramatic increase in mid-lift airflow and increased piston-to-valve and valve-to-bore clearance that allow higher lift cams and larger diameter valves to be used without having to alter the bore size or fly cutting pistons. Other features include OE PI-style intake inlets, patented Fast As Cast™ intake/exhaust runners that deliver near CNC-ported airflow, fully CNC-profiled combustion chambers, bulletproof ¾ inch thick decks, four-bolt replaceable cam bearing journals, full ¾ inch-reach spark plugs, 1.840 inch/1.450 inch valves, powdered metal valve guides, ductile iron valve seats, lightweight chromemoly retainers, and die-forged locks, beehive valve springs, and Viton® fluoroelastomer valve seals. The Twisted Wedge 185 series heads fit all 1996-2004 4.6L/5.4L 2V Romeo and Windsor engines and accept all OE-type 2V camshafts, followers, lash adjusters, and valve covers. Furthermore, 8mm end holes in the heads ensure that most OE Ford front covers will fit. Twisted Wedge 185 heads have 90 lb. rate (installed height) springs for mildly modified engines. Bare cylinder head castings are also available.

These require timing cover bolt and stud kit TFS-51954TCB.
