Product Details

The Cometic C5489-027 is a high-performance 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 4.100-inch bore diameter and a compressed thickness of .027 inches, making it ideal for stock and mildly modified street engines.

Key Features:

  • Multi-Layer Steel construction provides superior sealing and durability
  • 4.100-inch bore diameter accommodates stock and slightly overbored cylinders
  • .027-inch compressed thickness for proper compression ratio maintenance
  • Advanced MLS technology allows gasket to move with the engine while maintaining seal integrity
  • Embossed stainless steel layers with Viton rubber coating for exceptional sealing
  • Designed to handle thermal expansion and cylinder pressure variations
  • Compatible with LS1, LS2, LS3, and LS6 Gen-3/4 small block V8 engines

Cometic MLS head gaskets are a proven choice for engine builders and performance enthusiasts who demand reliable sealing under demanding conditions. The multi-layer steel construction distributes load evenly across the sealing surface while maintaining the ability to conform to minor surface imperfections, ensuring a leak-free seal between the cylinder head and engine block.

The right product is important- when found, it lessens the time and effort of getting the vehicle back running.

It went well. I'm hoping the tools are great.-----

The website was very easy to navigate. I'm kinda going into buying these wheels blind because I don't know the size or bolt pattern.
