Product Description

Once you see Trick Flow's Twisted Wedge 185cc cylinder heads for Ford 4.6L/5.4L 2V engines in action, you'll agree they are the only aftermarket 2V heads worth bolting on to your modular-powered Ford. 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 flycutting 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 in. thick decks, four-bolt replaceable cam bearing journals, full ¾ in.-reach spark plugs, 1.840 in./1.450 in. 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. Cylinder heads are available with 38cc or 44cc combustion chambers. Both versions deliver about 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 heads castings are also available.

5 Stars   Nice set of Heads
By on 3/20/2016
I purchased these heads for my 2001 GT Automatic. These heads are pricey (they are OHC Heads after all so it's expected) but they are extremely nice and designed beautifully. My set-up is pretty much all the bolt-on basics; Stock Cams, K&N Cold Air, 75mm Accufab TB & Plenum, PP Intake Manifold, Steeda UDPs, JBA Shorty O/R Exhaust, Aluminum DS, and tuned with a SCT tuner. I haven't been on the dyno to see what power gains were made (251RWHP was PRE HEAD INSTALL) hoping to see a 30-40hp increase over that old number when I get it on the dyno soon. As far as a seat of my pants feel I can definitely noticed an increase in power. The only CON I could find was after these heads were installed I had oil burn off on start-up, I'm guessing due to the increase in compression creating more pressure on the crankcase shooting my oil back up to the intake manifold. This was easily solved with a Moroso oil separator. Overall If you can afford this type of mod do it, or do the top-end kit if you want the most power.

Yes, I would recommend this item to a friend!

5 Stars   Awesome Heads!
By on 1/5/2015
Had these installed on my 1996 4.6L Thunderbird. These with the NPI bottom end produce a calculated 11.2:1 static compression ratio. With stock cams and exhaust, and stock style PI intake manifold, it put out 268 RWHP through an automatic. The best money I've spent on this setup to date. They even outflow ported PI heads. Win!
