  1. Trick Flow 4.6L/5.4L Twisted Wedge® Head with 38cc Combustion Chambers and 90 lb. Single Valve Springs, 185cc Intake Runners (Each)
    $1,414.99

    Trick Flow® Twisted Wedge® 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 185 heads are intended for mildly modified engines. The heads fit all 2V Romeo and Windsor engines and accept all OE-style camshafts, followers, lash adjusters, valve covers, and most OE Ford front covers.
