This precision-manufactured gasket features a .051-inch compressed thickness and is designed for a 3.860-inch bore diameter, making it ideal for stock and performance engine builds.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability under high combustion pressures
• .051-inch (1.3mm) compressed thickness for precise compression ratio tuning
• 3.860-inch bore diameter accommodates standard and slightly overbored Y-Block cylinders
• Left-hand side (LHS) gasket for driver's side cylinder bank
• Embossed stainless steel layers with proprietary coating ensure optimal sealing
• Designed to withstand extreme temperatures and pressures in performance applications
• Eliminates gasket failure common with traditional composite gaskets

Cometic MLS gaskets feature multiple layers of stainless steel with advanced coatings that micro-seal imperfections in the block and head surfaces. This design allows for controlled compression and excellent recovery properties, making them the preferred choice for high-performance and race engine builds. Compatible with classic Ford Y-Block V8 engines found in 1954-1964 Ford and Mercury vehicles.

Note: This gasket is sold individually for the left-hand (driver's) side. A matching right-hand side gasket is required for complete cylinder head installation.
