Trickflow Super 23 Cylinder Heads, SB Chevy, 195cc Intake, 62cc Chambers, 1.460" Dual Springs, Center Bolt
TFS-30410007
Bolt-on aluminum cylinder heads for the price of cast iron!
Dyno-tested on a 383 cu. in. engine, Trick Flow® 64cc Super 23 (TM) street/strip aluminum cylinder heads made 460 hp and 451 ft.-lbs. of torque, 40 more horsepower and 11 ft.-lbs. more torque than the same engine with GM L98 Corvette heads. The Trick Flow® Super 23 (TM) street/strip cylinder heads also made more power than Dart's Iron Eagle and World Product's Sportsman II cast iron heads. The Super 23 (TM) street/strip heads are direct-fit, high performance replacements for most original equipment factory heads and accept most factory accessories. They combine angled spark plugs, a choice of 62cc as-cast or 64cc and 72cc CNC-profiled combustion chambers, 2.020 in./1.600 in. stainless steel valves, hardened exhaust valve seats for unleaded gas, and 195cc intake ports with a high-velocity, small cross-section design to promote low-rpm torque without sacrificing higher rpm horsepower. The Super 23 (TM) street/strip heads are available with three spring sizes: 1.250 in. single for cams with up to .480 in. lift, 1.470 in. single for cams with up to .540 in. lift, and 1.460 in. dual for cams with up to .600 in. lift. They come fully assembled with valves, valve springs, locks, retainers, rocker arm studs, and guideplates. Cylinder head part numbers TFS-30400001, TFS-30400002, TFS-30400005, and TFS-30400006 are 50-state emissions-legal under CARB E.O. number D-369-4. Sold individually.
