Trick Flow® Super 23® 195 cylinder heads give you performance that closely matches CNC-ported cylinder heads—for about the same price as ordinary cast heads! Ideal for 302 to 406 c.i.d. engines, the Super 23® 195 heads feature high-velocity, small cross-section intake runners to promote low-rpm torque and high-rpm horsepower. Fast As Cast® runners deliver near-CNC-ported flow and performance. Angled spark plugs, raised valve cover rails, and extra-thick decks and walls for porting round-out the features.

Trick Flow Super 23 195 heads are a direct fit, high performance replacement for factory heads and accept most original accessories. They are emissions-legal under CARB E.O. #D-747-1 for 1995 and earlier GM vehicles with Chevy 262-350 engines. The heads are available fully assembled or as bare castings. Sold individually.
