Cometic C5333-089 GM Big Block MLS Cylinder Head Gasket Bore - V8 4.540

The Cometic C5333-089 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for GM Generation V and Generation VI Big Block V8 engines. This precision gasket features a 4.540-inch bore diameter and a compressed thickness of .089 inches, providing an optimal seal between the cylinder head and engine block.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• 4.540-inch bore diameter for proper cylinder clearance
• .089-inch compressed thickness for precise compression control
• Designed for GM Gen-V and Gen-VI Big Block V8 engines
• Advanced material technology resists blow-out and combustion leaks
• Excellent temperature resistance and dimensional stability
• Accommodates minor surface imperfections for reliable sealing

Cometic MLS gaskets utilize multiple layers of stainless steel with specialized coatings to create a superior seal that withstands extreme cylinder pressures and temperatures. The gasket's design allows for thermal expansion and contraction while maintaining constant sealing pressure across the entire surface. Ideal for performance builds, race applications, and engine rebuilds where reliability is critical.
