The Cometic C4634-027 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Honda F20B engines. This precision-manufactured gasket features an 86mm bore diameter and a compressed thickness of .027 inches, providing exceptional sealing capability for both stock and modified applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior strength and durability
• 86mm bore diameter designed for Honda F20B engine specifications
• .027-inch compressed thickness for precise compression control
• Advanced embossment technology ensures even load distribution
• Superior resistance to combustion pressure and thermal expansion
• Accommodates stock and mild performance builds

Cometic MLS head gaskets utilize multiple layers of stainless steel with specialized coatings to create a gasket that can withstand extreme cylinder pressures and temperatures. The embossed design provides targeted sealing around combustion chambers, oil passages, and coolant ports while allowing the gasket to move with the engine's thermal expansion and contraction cycles, preventing blown gaskets and maintaining optimal sealing performance.
