Trick Flow’s Super 23 230 cylinder heads represent the best value in small block Chevy racing technology. That’s because they are the closest thing you can get to 18° cylinder head performance in a 23° design. The Super 23 230 heads work best on 400 cubic inch and larger engines. The heads come standard with Trick Flow’s advanced CNC Competition Ported runner design that features fully CNC-profiled combustion chambers and runners with a premium high resolution surface finish for maximum flow and performance. Additional highlights include angled spark plugs, extra-thick decks and walls for porting, and raised valve cover rails.
To make swapping cylinder heads less costly and time-consuming, Trick Flow designed the Super 23 230 heads to use all standard small block valvetrain parts and headers. Cylinder heads are available fully assembled or as bare castings. Sold individually.
