Trick Flow® Twisted Wedge® Track Heat® 185 Cylinder Heads for Ford 4.6L/5.4L 2V

Trick Flow® Twisted Wedge® Track Heat® 185 series cylinder heads are the best aftermarket heads for modular-powered Fords. The secret: Twisted Wedge combustion chambers and intake valves moved on the opposite side of the cam. The result is dramatic increases in mid-lift airflow, piston-to-valve clearance, and valve-to-bore clearance for using higher lift cams and larger valves without altering bore size or flycutting pistons. Other exclusive features include OE PI-style intake inlets, Fast As Cast® runners that deliver near-CNC-ported airflow, CNC-profiled combustion chambers, 3/4" thick decks, patented replaceable cam bearing journals, and 3/4"-reach spark plugs.

Twisted Wedge Track Heat 185 heads are intended for engines with power adders and/or high rpm applications. They fit all 2V Romeo and Windsor engines and accept all OE-style camshafts, followers, lash adjusters, valve covers, and most OE Ford front covers. The heads are available fully assembled or as bare castings. Sold individually.
