Cometic C5703-032 GM LSX Small Block Cylinder Head Gasket Bore MLX - Gen-4 V8 4.165 032

The Cometic C5703-032 is a premium Multi-Layer Stainless Steel (MLX) cylinder head gasket specifically engineered for GM LSX Gen-4 small block V8 engines. This left-hand side (LHS) gasket features a 4.165-inch bore diameter and a compressed thickness of .032 inches, providing exceptional sealing performance for high-performance and racing applications.

Key Features:

• Multi-Layer Stainless Steel (MLX) construction for superior durability and heat resistance
• 4.165-inch bore diameter optimized for LSX Gen-4 engine specifications
• .032-inch compressed thickness for precise combustion chamber sealing
• Left-hand side (LHS) application for proper engine assembly
• Engineered to withstand extreme cylinder pressures in boosted and high-compression applications
• Embossed stainless steel layers with advanced sealing coatings

Cometic MLX gaskets utilize multiple layers of stainless steel with proprietary coating technology to create a gasket that rebounds and conforms to sealing surfaces better than traditional composite gaskets. This design makes them ideal for engines with increased cylinder pressures from forced induction, nitrous oxide, or high compression ratios. The gasket's construction allows it to maintain its sealing integrity even under thermal cycling and extreme combustion pressures.
