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. Super 23 230 heads are designed for 400 cubic inch and larger engines and use standard small block valvetrain parts and headers. Highlights include angled spark plugs, extra-thick decks and walls for porting, and raised valve cover rails. You can get your Super 23 230 heads in two flavors: CNC Street Ported and CNC Competition Ported. Heads with CNC Street Ported runners feature fully CNC-machined runners and combustion chambers with a standard resolution surface finish for significant performance gains over regular cast heads. Super 23 230 heads with CNC Competition Ported runners have CNC-profiled combustion chambers and runners with a premium high resolution surface finish for maximum flow and performance. Cylinder heads are available fully assembled or as bare castings. 1962-69 Chevy small block Gen I 5.4L/327
