Product Details

The Cometic C5809-140 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Oldsmobile Gen-2 Rocket V8 engines. This high-performance gasket features a 4.200-inch bore diameter and a compressed thickness of .140 inches, making it ideal for both stock rebuilds and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.200-inch bore diameter for proper cylinder sealing
  • .140-inch compressed thickness
  • Designed specifically for Oldsmobile Gen-2 Rocket V8 engines
  • Handles extreme cylinder pressures in high-performance and forced induction applications
  • Coated with Cometic's proprietary viton rubber bead for enhanced sealing
  • Resists blowout and maintains seal integrity under thermal cycling

Cometic MLS gaskets are constructed from multiple layers of stainless steel, providing the flexibility to conform to imperfect sealing surfaces while maintaining the strength to withstand extreme combustion pressures. The advanced coating technology ensures optimal sealing between the block and cylinder head, making this gasket an excellent choice for both street and racing applications.
