Product Details

The Cometic C4146-120 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for BMC 1275 A-Series engines. This high-performance gasket features a 73mm bore diameter and .120" (3.0mm) compressed thickness, making it ideal for performance builds and engine rebuilds requiring precise compression control.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 73mm bore diameter for proper cylinder sealing
  • .120" compressed thickness allows for compression ratio adjustment
  • Engineered specifically for BMC 1275 A-Series engines
  • Resistant to high temperatures and combustion pressures
  • Eliminates the need for retorquing after initial installation

Cometic's MLS gaskets utilize multiple layers of stainless steel with proprietary coatings to provide maximum sealing performance under extreme conditions. The embossed layers create a seal around combustion chambers, oil passages, and coolant passages while accommodating surface imperfections and thermal expansion. This gasket is an excellent choice for both street and racing applications where reliability and performance are critical.
