Trick Flow Twisted Wedge Cylinder Head with 185cc intake runners and 38cc combustion chambers for 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003 and 2004 Mustangs with 4.6L 2V engines.

Trick Flow Twisted Wedge 185cc cylinder heads (TFS-51910001-M38) 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 fly cutting pistons.

Features and Benefits:
- Revised Performance Design
- 38cc Combustion Chambers
- Pre-Assembled
- High Port Flow

Achieve great naturally aspirated power! 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. 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.
