Trick Flow® Super 23® 175 cylinder heads give you performance that closely matches CNC-ported cylinder heads—for about the same price as ordinary cast heads! Made to outperform factory small block Chevy heads on 283-350 c.i.d. street performance engines, the Super 23 175 heads feature small cross-section intake runners to promote low-rpm torque and high-rpm horsepower on small bore engines. Fast As Cast® runners duplicate the runner profile and performance levels of CNC-ported heads. Other features include angled spark plugs, raised valve cover rails, and extra-thick decks and walls for porting. Trick Flow Super 23 175 heads are a direct fit, high performance replacement for factory heads and accept most original accessories. The heads are 50-state emissions-legal under CARB E.O. Number D-369-6 for 1995 and earlier GM vehicles with Chevy 262–350 engines. The heads are available fully assembled or as bare castings.
