*image is only a representation and may not be accurate

Trick Flow Twisted Wedge® Race 195 cylinder heads are perfect for big bore engine builds, superchargers and turbos, high compression E85, big shot nitrous oxide, and other mega-power combinations.

The heads have the same features of the Twisted Wedge 185 series heads—Twisted Wedge combustion chambers, altered intake valve positions, OE PI-style intake inlets, CNC-profiled combustion chambers, 3/4" thick decks, patented replaceable cam bearing journals*, and 3/4"-reach spark plugs—but 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.
