Get the performance you need with the Chevrolet Performance Cylinder Head. Cylinder heads sit on top of the cylinder block to form the combustion chamber, and have ports for the fuel/air mixture and exhaust gases to travel through. The Gen V/Gen VI bare cylinder head is made of cast iron and features 3/8-inch accessory bolt holes, rectangular intake ports, heat risers, and a non-adjustable rocker arm design. It is machined for 2.180-inch/1.880-inch (3/8-inch stems) valves, and is assembled with valve springs, seals, retainers, locks, and valve spring shims. It will not work on production Mark IV cylinder blocks. No matter what you're driving or what you're building, Chevrolet Performance has a wide range of engines, parts and other accessories to help you fulfill your project-vehicle dream.

Features:
  • Rectangular intake ports with a large volume designed to enhance high-RPM horsepower-ideal for big-block enthusiasts who want more power from a street car that sees a lot of drag-strip action
  • Direct replacements on most 1990-and-later GM big-block 454-cubic-inch and 502-cubic-inch engines
  • Will not work on production Mark IV cylinder blocks
  • Meets original equipment manufacturer specifications
  • 118cc combustion chamber
  • 325cc intake runner volume
  • Sits on top of the cylinder block, forming the combustion chamber
