Product Details

The Cometic C5330-056 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Mark IV Big Block V8 engines. This precision gasket features a 4.540-inch bore diameter and a compressed thickness of .056 inches, providing an optimal seal for high-performance and racing applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior strength and durability
  • 4.540-inch bore diameter for proper cylinder sealing
  • .056-inch compressed thickness for accurate compression ratio tuning
  • Designed specifically for Chevrolet Mark IV Big Block V8 engines
  • Exceeds OEM specifications for high-performance applications
  • Provides excellent resistance to extreme temperatures and pressures
  • Eliminates re-torquing requirements common with composite gaskets

Cometic MLS gaskets utilize multiple layers of stainless steel with a Viton rubber coating to create a superior seal that can withstand the extreme pressures and temperatures of high-performance engines. The embossed layers provide additional micro-sealing at the combustion chamber while allowing for minor surface imperfections. This gasket is ideal for street performance, racing, and forced induction applications where reliability and consistent sealing are critical.
