Trick Flow Super 23® 195 cylinder heads for small block Chevy are a direct fit, high performance replacement for factory heads and accept most original accessories. Ideal for 302- 406 c.i.d. engines, these 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 for about the same price as regular cast heads. Angled spark plugs, raised valve cover rails, and extra-thick decks and walls for porting round-out the features.
Super 23 195 heads are emissions-legal under CARB E.O. #D-747-1 for 1995 and earlier GM vehicles with Chevy 262-350 engines. They are available fully assembled or as bare castings. Sold individually.
