Product Details

The Cometic C5129-060 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Oldsmobile 370 and 371 cubic inch Gen-1 Rocket V8 engines, including the legendary J-2 Golden Rocket variant. This gasket features a .060" compressed thickness and accommodates a 4.190" bore diameter.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .060" compressed gasket thickness for precise compression ratio tuning
  • 4.190" bore diameter designed for Oldsmobile Rocket V8 applications
  • Compatible with 370 and 371 cubic inch Gen-1 Oldsmobile engines
  • Engineered for J-2 Golden Rocket and standard Rocket V8 configurations
  • Provides exceptional resistance to extreme cylinder pressures
  • Maintains seal integrity under thermal cycling and engine vibration

Cometic MLS head gaskets utilize multiple layers of stainless steel with advanced coating technology to create a gasket that conforms to sealing surfaces while withstanding the demanding conditions of high-performance engines. The .060" thickness allows engine builders to fine-tune compression ratios for optimal performance in classic Oldsmobile V8 builds.
