Once you see Trick Flow® Twisted Wedge® 185 cylinder heads for Ford 4.6L/5.4L 2V engines in action, you'll agree that they are the only aftermarket 2V heads worth bolting on to your modular-powered Ford. The power comes from their Twisted Wedge® 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 flycutting pistons. 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. The cylinder heads are available with 38cc or 44cc combustion chambers. Both versions deliver about a 10:1 compression on a stock short block, depending on the piston used. Twisted Wedge® 185 heads have 90 lb. rate (installed height) springs for mildly modified engines. Bare cylinder head castings are also available.

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 3/4 in. thick decks
* 4-bolt replaceable cam bearing journals
* Full 3/4 in. reach spark plugs
* 1.840 in./1.450 in. valves
* Powdered metal valve guides
* Ductile iron valve seats
* Lightweight chromoly retainers
* Die-forged locks
* Beehive valve springs
* Viton® fluoroelastomer valve seals
