Product Details

The Cometic C5788-040 is a multi-layer steel (MLS) cylinder head gasket engineered specifically for GM LS Gen-3 and Gen-4 small block V8 engines, including LS1, LS2, LS3, and LS6 applications. This precision gasket features a .040" compressed thickness and is designed for engines with a 3.910" bore diameter, making it ideal for performance builds using Darton MID (Multiple Interlocking Design) sleeves.

Key Features:

  • Multi-layer steel construction provides superior sealing and durability under extreme cylinder pressures
  • 3.910" bore diameter accommodates oversized or sleeved engine configurations
  • .040" compressed thickness allows for precise compression ratio tuning
  • Specifically engineered for use with Darton MID sleeve systems
  • Compatible with GM LS1, LS2, LS3, and LS6 Gen-3/Gen-4 small block V8 engines
  • Manufactured to OEM specifications with enhanced performance characteristics

Cometic's MLS gaskets utilize multiple layers of stainless steel with a Viton rubber coating to create a superior seal that withstands the increased cylinder pressures found in high-performance and forced induction applications. The .040" thickness makes this gasket an excellent choice for builders looking to fine-tune compression ratios or accommodate deck height variations in sleeved blocks.
