This gasket features a compressed thickness of .051 inches and a 4.160-inch bore diameter, making it ideal for stock rebuilds and mild performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability
  • .051-inch compressed thickness for precise deck height control
  • 4.160-inch bore diameter designed for Pontiac big block V8 engines
  • Excellent resistance to combustion pressure and extreme temperatures
  • Compatible with aluminum and iron cylinder heads
  • Embossed stainless steel layers ensure optimal sealing around combustion chambers and coolant passages
