Product Details

The Cometic C15421-043 is a precision-engineered copper cylinder head gasket designed specifically for Ford 385 Series engines. This high-performance gasket features a 4.520" bore diameter and .043" (43 thousandths) compressed thickness, providing exceptional sealing and durability for demanding applications.

Key Features:

  • Premium copper construction for superior heat dissipation and conformability
  • 4.520" bore diameter optimized for Ford 385 Series big block engines
  • .043" compressed thickness for precise compression control
  • Eliminates gasket failure in high-performance and racing applications
  • Conforms to minor surface imperfections for reliable sealing
