Cometic C5935-062 GM LSX Small Block MLS Head Gasket Bore - Gen-4 V8 4.185

The Cometic C5935-062 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for GM LSX Gen-4 small block V8 engines. This gasket features a 4.185-inch bore diameter and .062-inch compressed thickness, providing excellent sealing performance for high-performance and racing applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior durability and sealing
• 4.185-inch bore diameter optimized for LSX Gen-4 engines
• .062-inch (1.57mm) compressed gasket thickness
• Compatible with right-hand side (RHS) cylinder head configurations
• Engineered to withstand extreme cylinder pressures and temperatures
• Provides consistent clamping pressure across the entire sealing surface

Cometic's MLS gaskets are constructed from multiple layers of stainless steel, with embossed sealing beads around combustion chambers, coolant passages, and oil return holes. This design allows the gasket to recover and maintain sealing integrity even under thermal cycling and extreme performance conditions. The embossments act as active seals that compensate for minor surface imperfections and cylinder head movement.

This gasket is ideal for engine builders and performance enthusiasts working with GM's popular LSX Gen-4 platform, including engines like the LS2, LS3, LS7, and other Gen-4 variants. Proper surface preparation is essential for optimal performance—surfaces should be flat, smooth, and free of imperfections.
