This premium gasket features a 4.200-inch bore diameter and .089-inch compressed thickness, making it ideal for performance builds and high-compression applications.

Key Specifications:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.200-inch bore diameter accommodates overbored blocks
  • .089-inch compressed thickness for precise compression ratio tuning
  • Designed for 18-degree and 23-degree cylinder heads
  • Round bore configuration with integrated steam holes for proper coolant circulation

Cometic's MLS gaskets feature multiple layers of stainless steel with elastomeric coatings that provide maximum sealing under extreme cylinder pressures and temperatures.

This gasket is an excellent choice for street performance, racing, and forced induction applications where reliability is critical.
