Trick Flow Twisted Wedge® Race 195 cylinder heads are perfect for big bore Ford Modular 2V engine builds as well as engines with superchargers or turbos, high compression E85, big shot nitrous oxide, and other mega-power combinations. The secret lies in the 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.

Trick Flow Twisted Wedge Race 195 heads have fully CNC Competition Ported runners with a premium high resolution surface finish for ultimate performance. Larger, stronger valves and race-duty valvetrain components give these heads 8,000-plus rpm capability. Other features include 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 Race 195 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. Sold individually.
