This gasket features a 4.380-inch bore diameter and a compressed thickness of .027 inches, making it ideal for performance builds requiring precise deck height control and superior sealing.

Key Features:

• Multi-Layer Steel construction for maximum durability and heat resistance
• 4.380-inch bore diameter accommodates stock and mild overbore applications
• .027-inch compressed thickness for precise deck height management
• Advanced MLS design provides superior sealing under extreme cylinder pressures
• Eliminates bore distortion and maintains sealing integrity through thermal cycling
• Compatible with Chrysler B series (361, 383, 400) and RB series (413, 426, 440) V8 engines
• Suitable for street performance and racing applications

Cometic MLS gaskets utilize multiple layers of stainless steel with advanced coating technology to create a gasket that maintains seal integrity through repeated heat cycles and high-boost applications. The MLS design allows the gasket to move with the engine's thermal expansion while maintaining constant pressure on the sealing surface.
