Product Details

The Cometic C5846-070 is a premium multi-layer steel (MLS) cylinder head gasket engineered specifically for Pontiac 400, 428, and 455 cubic inch V8 engines. This gasket features a 4.380-inch bore diameter and a .070-inch compressed thickness, making it ideal for high-performance and modified engines requiring precise sealing and durability.

Key Features:

  • Multi-layer steel construction provides superior sealing and conformability
  • .070-inch compressed thickness allows for custom compression ratio tuning
  • 4.380-inch bore diameter accommodates standard and slightly overbored cylinders
  • Embossed stainless steel outer layers with a steel inner core resist corrosion and extreme temperatures
  • Eliminates gasket failure common with traditional composite gaskets in high-performance applications
  • Designed for use with performance cylinder heads and engine builds

Cometic MLS gaskets are the preferred choice for engine builders and enthusiasts who demand maximum reliability under extreme operating conditions. The multiple layer design distributes clamping load evenly while maintaining excellent recovery properties through countless heat cycles.
