Product Details

The Cometic C5641-051 is a premium multi-layer steel (MLS) cylinder head gasket engineered specifically for GM/Mercury Marine 1050 Gen-IV big block V8 applications. This high-performance gasket features a 4.600-inch bore diameter and a compressed thickness of .051 inches, providing exceptional sealing capability for marine and high-performance engines.

Key Features:

  • Multi-layer steel (MLS) construction for superior strength and reliability
  • 4.600-inch bore diameter optimized for Gen-IV big block applications
  • .051-inch compressed thickness for precise engine sealing
  • Includes two slotted lifter valley bolt holes for proper installation
  • Designed for GM and Mercury Marine Gen-IV V8 engines
  • Advanced material technology resists blow-out and provides consistent torque retention

Cometic's MLS gaskets feature multiple layers of stainless steel with specialized coatings that allow the gasket to conform to irregular sealing surfaces while maintaining excellent recovery properties. This design accommodates thermal expansion and contraction while preventing coolant and combustion gas leakage, making it ideal for both stock and modified marine engine applications.
