Product Details

The Cometic C5985-040 is a precision-engineered Multi-Layer Steel (MLX) cylinder head gasket designed specifically for GM LS9 and LSA Gen-4 small block V8 engines. This high-performance gasket features a .040" compressed thickness and 4.100" bore diameter, making it ideal for supercharged applications and high-boost builds.

Key Features:

  • Multi-Layer Steel (MLX) construction for superior sealing and durability
  • .040" compressed thickness provides precise deck height control
  • 4.100" bore diameter accommodates LS9/LSA cylinder dimensions
  • Right-hand side (RHS) configuration for proper installation orientation
  • Engineered for high-performance and forced-induction applications
  • Resists blowout under extreme cylinder pressures

Cometic's MLX gaskets utilize multiple layers of stainless steel with advanced coating technology to provide exceptional sealing performance. The embossed layers compress and recover to maintain optimal sealing pressure through heat cycles and engine vibration, making this gasket an excellent choice for LS9 and LSA builds requiring reliability under demanding conditions.
