Product Details

The Cometic C4323-060 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Nissan RB30 inline-six engines. Engineered with a precision 87mm bore diameter and .060" (1.5mm) compressed thickness, this gasket provides exceptional sealing for both stock and modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction with multiple layers of stainless steel for superior strength and durability
  • 87mm bore diameter designed for Nissan RB30 engine specifications
  • .060" compressed gasket thickness for precise compression ratio tuning
  • Advanced embossment technology ensures optimal cylinder sealing under extreme pressures
