Product Details

The Cometic C5755-066 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Buick Big Block V8 engines. This high-performance gasket features a .066" compressed thickness and accommodates a 4.400" cylinder bore diameter, making it ideal for performance builds and engine rebuilds requiring reliable sealing under high compression and extreme temperatures.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior strength and durability
  • .066" compressed gasket thickness for precise compression ratio tuning
  • 4.400" bore diameter designed for Buick Big Block V8 applications
  • Exceptional resistance to combustion pressure and thermal cycling
  • Provides consistent clamping load across the entire sealing surface
  • Embossed stainless steel layers with advanced coating technology

Cometic MLS gaskets are engineered to withstand the demanding conditions of high-performance and racing applications. The multiple layers of stainless steel provide flexibility to conform to minor surface imperfections while maintaining robust sealing integrity. The advanced coatings resist micro-welding and allow for proper gasket movement during thermal expansion, ensuring a long-lasting, leak-free seal for your Buick Big Block engine.
