Product Details

The Cometic C5635-120 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for GM and Mercury Marine Big Block V8 Gen-IV, Gen-V, and Gen-VI engines. This precision gasket features a .120-inch (120 thousandths) compressed thickness and is designed for engines with a 4.530-inch cylinder bore.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.530-inch bore diameter for proper cylinder fitment
  • .120-inch compressed thickness for optimal compression ratio tuning
  • Compatible with Gen-IV, Gen-V, and Gen-VI GM/Mercury Marine Big Block V8 engines
  • Designed for engines with 4 bolts in the lifter valley configuration
  • Premium gasket material resists high temperatures and combustion pressures

Cometic MLS head gaskets feature multiple layers of stainless steel with a Viton rubber coating, providing excellent conformability to sealing surfaces while maintaining the strength needed for high-performance and marine applications. The unique design allows for minor surface imperfections while preventing coolant and oil leaks. Ideal for engine rebuilds, performance upgrades, and marine engine overhauls.

Best prison the Internet and quick order fulfillment. Glad to have found Autoplicity!

Ordered 4 race ramps flatstoppers for winter storage of my Dodge Viper. Product prevents flat spots on auto tires that are stored more than 30 days. Order process was extremely easy, product was promptly shipped. I'll definately do business with Autoplicity in the future.
