Product Details

The Cometic C5937-056 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for AMC 390 and 401 cubic inch Gen-3 V8 engines. This precision-manufactured gasket features a 4.250-inch bore diameter and .056-inch compressed thickness, providing exceptional sealing performance for stock and modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.250-inch bore diameter optimized for AMC 390/401 engines
  • .056-inch compressed thickness for precise compression ratio tuning
  • Designed for Gen-3 AMC V8 applications
  • Advanced material composition resists corrosion and extreme temperatures
  • Eliminates gasket failure from blown head gaskets in high-performance builds

Cometic's MLS gaskets feature multiple layers of stainless steel with unique embossments that enable the gasket to conform to irregular sealing surfaces. The proprietary coating enhances the seal while allowing minor movement between the head and block, making this gasket ideal for both street and performance applications where reliability is critical.
