Product Details

The Cometic C5720-066 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Buick 3800 Series II and Series III V6 engines. This precision-manufactured gasket features a .066" compressed thickness and 3.840" bore diameter, designed for the left-hand side (driver side) cylinder head.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under high-stress conditions
  • Precision-cut .066" (1.68mm) compressed thickness for optimal compression ratio and sealing
  • 3.840" bore diameter accommodates stock and mild performance applications
  • Application-specific design for Buick 3800 Series II/III V6 engines (LHS/driver side)
  • Cometic's MLS technology features multiple layers of stainless steel with elastomeric coatings for maximum conformability
  • Resists combustion chamber pressure and extreme temperatures better than composite gaskets
  • Reusable design allows for easier disassembly and reassembly during engine maintenance

Cometic MLS gaskets are the choice of professional engine builders and performance enthusiasts who demand reliable sealing in demanding applications. The multi-layer design provides excellent recovery characteristics and maintains seal integrity through repeated heat cycles, making this gasket ideal for both street and performance builds of the popular GM 3800 V6 platform.
