Product Details

The Cometic C5475-070 is a premium Multi-Layer Steel (MLS) cylinder head gasket designed specifically for GM LS Gen III and Gen IV small block V8 engines, including LS1, LS2, LS3, and LS6 applications. Engineered with a .070" compressed thickness, this gasket provides optimal sealing performance for both stock and modified engines.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 3.910" bore diameter accommodates standard and slightly overbored cylinders
  • .070" compressed thickness allows for precise compression ratio tuning
  • Compatible with LS1, LS2, LS3, and LS6 Gen III/IV small block V8 engines
  • Embossed stainless steel outer layers with multiple inner layers for maximum sealing
  • Excellent resistance to extreme temperatures and pressures
  • Accommodates minor deck surface imperfections

Cometic MLS gaskets are the preferred choice of engine builders and racers who demand reliable sealing under demanding conditions. The multi-layer design allows the gasket to conform to cylinder head and block irregularities while maintaining consistent clamping pressure across the entire combustion seal.
