Cometic H1518SP9051S MLS Head Gasket 4.080" Bore .051" Thickness LS Engine

The Cometic H1518SP9051S is a Multi-Layer Steel (MLS) head gasket constructed from multiple layers of stainless steel for superior strength and durability. This gasket is designed for 4-bolt LS engines with a 4.080-inch bore diameter and .051-inch compressed thickness.

Key Features:

• Multi-layer construction with embossed layers of proprietary high temperature coated and uncoated stainless steel
• Load-controlled embossments that conform load distribution across the sealing area
• Requires less clamp load and creates less bore distortion than conventional gaskets
• Proprietary high temperature coatings with embossments provide a micro seal for fluids
• 4.080-inch bore diameter for precise fitment
• .051-inch compressed thickness for accurate compression ratio tuning

Cometic MLS head gaskets are engineered to meet the demands of high-performance and racing applications, providing reliable sealing under extreme pressure and temperature conditions. The multi-layer steel construction allows the gasket to adapt to surface imperfections while maintaining consistent sealing performance throughout the engine's operating range.
