Product Details

The Cometic C4146-070 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket specifically engineered for BMC 1275 A-Series engines. This precision-manufactured gasket features a 73mm bore diameter and .070" (1.78mm) compressed thickness, making it ideal for performance builds and engine rebuilds requiring enhanced sealing capabilities.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under high compression and temperature conditions
  • 73mm bore diameter designed specifically for BMC 1275 A-Series applications
  • .070" compressed thickness allows for precise compression ratio tuning
  • Embossed stainless steel layers with Viton rubber sealing beads ensure optimal sealing performance
  • Resists blow-out and withstands extreme cylinder pressures better than traditional composite gaskets
  • Ideal for performance applications, forced induction, and high-compression builds

Cometic gaskets are trusted by professional engine builders and racers worldwide for their exceptional quality and reliability. The MLS design accommodates minor surface imperfections while maintaining a robust seal, making this gasket an excellent choice for classic Mini, Morris, Austin, and other BMC A-Series powered vehicles.
