Cometic C5986-044 GM Small Block MLS Cylinder Head Gasket - LS9/LSA Gen-4 V8

The Cometic C5986-044 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for GM LS9 and LSA Gen-4 small block V8 engines. This precision-manufactured gasket features a .044" compressed thickness and is designed for the left-hand side (driver side) cylinder head installation.

Key Specifications:

• Bore size: 4.100 inches for optimal sealing on LS9/LSA applications
• Compressed thickness: .044 inches (1.12mm)
• Multi-Layer Steel (MLS/MLX) construction for superior strength and durability
• Left-hand side (LHS) gasket - order two for complete engine rebuild
• Designed for GM LS9 supercharged and LSA engines

Cometic's MLS gaskets utilize multiple layers of stainless steel with a Viton rubber coating, providing exceptional resistance to extreme cylinder pressures and temperatures. The advanced design allows for slight movement between layers to absorb minor surface imperfections while maintaining a positive seal. This gasket is ideal for both high-performance street applications and racing engines running elevated boost levels or compression ratios.

Note: This gasket is sold individually for the left-hand cylinder head. A matching right-hand side gasket is required for complete installation.
