Product Details

The Cometic C5808-027 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Oldsmobile Gen-2 Rocket V8 engines including the 330, 350, 400, 403, and 455 cubic inch displacements. This precision-manufactured gasket features a 4.125-inch bore diameter and a compressed thickness of .027 inches, making it ideal for stock to mild performance builds.

Cometic MLS head gaskets are constructed from three layers of stainless steel, featuring embossed outer layers coated with Viton for superior sealing and an uncoated center shim layer. This multi-layer design requires less clamp load than conventional gaskets while creating less bore distortion and providing optimal load distribution across the entire sealing surface. The proprietary high-temperature coating combined with embossments creates a micro seal for fluids against both the cylinder head and engine block surfaces.

These gaskets are engineered to perform in demanding conditions and are ideal for both aluminum-to-aluminum and aluminum-to-cast iron applications. The MLS construction provides excellent rebound characteristics and corrosion resistance, ensuring long-term reliability even in high-output engine applications. No additional sealants are required for installation.

Specifications:

  • Material: Multi-Layer Stainless Steel (MLS)
  • Bore Size: 4.125 inches (round)
  • Compressed Thickness: .027 inches
  • Number of Layers: 3
  • Coating: Viton on outer layers
  • UPC: 191070049058

Note: This gasket is sold individually. Two gaskets are required for a complete V8 engine installation.
