The Cometic C5333-054 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for GM Generation V and VI Big Block V8 engines. This high-performance gasket features a 4.540-inch bore diameter and a compressed thickness of .054 inches, providing exceptional sealing performance for demanding applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior durability and combustion sealing
• 4.540-inch bore diameter optimized for GM Big Block V8 engines
• .054-inch compressed thickness for precise compression ratio tuning
• Compatible with Generation V and VI GM Big Block engines
• Advanced material design handles extreme cylinder pressures and temperatures
• Maintains consistent seal through thermal expansion and engine movement

Cometic's MLS gaskets utilize multiple layers of stainless steel with proprietary coatings to create a gasket that recovers quickly from compression cycles and resists blowout. The embossed layers provide multiple sealing points around combustion chambers, coolant passages, and oil return holes. This gasket is ideal for performance builds, boosted applications, and high-compression engines where OEM gaskets fall short.
