Trickflow Twisted Wedge Track Heat Ford 185cc, 150lb Cylinder Head 44cc 4.6l/5.4l 2v, Max Lift .650

Aluminum heads for Ford bracket racers. Trick Flow® Twisted Wedge® Track Heat® 185 series cylinder heads are the best aftermarket heads for Ford 2V Modular engines with power adders and/or high rpm applications. The heads feature CNC-profiled Twisted Wedge combustion chambers and intake valves moved to the opposite side of the cam. These features provide 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 Fast As Cast® runners that deliver near-CNC-ported airflow, OE PI-style intake inlets, patented replaceable cam bearing journals (no more junking heads because of trashed cams!), 3/4" thick decks, and 3/4"-reach spark plugs. Trick Flow Twisted Wedge Track Heat 185 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. The heads are available fully assembled or as bare castings. Price listed is per head, if you need a pair, order 2 of this item.
