Product Details

The Cometic C5754-056 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Buick Big Block V8 engines. This high-performance gasket features a 4.385-inch bore diameter and a compressed thickness of .056 inches, providing exceptional sealing capability for both stock and modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior strength and durability
  • 4.385-inch bore diameter optimized for Buick Big Block V8 engines
  • .056-inch compressed thickness for precise compression control
  • Advanced sealing technology prevents combustion gas leakage
  • Excellent thermal resistance and load distribution
  • Accommodates thermal expansion and cylinder head movement

Cometic MLS gaskets utilize multiple layers of stainless steel with strategically placed embossments to provide maximum sealing around combustion chambers, coolant passages, and oil ports. The design allows the gasket to withstand extreme cylinder pressures while maintaining proper engine sealing in high-performance and racing applications.
