This high-performance gasket features a compressed thickness of .045 inches and is designed for a 4.600-inch bore diameter with a siamese bore configuration.

Key Specifications:

• Compressed gasket thickness: .045 inches (45 thousandths)
• Bore diameter: 4.600 inches
• Siamese bore design for increased strength
• Multi-Layer Steel (MLS) construction
• Application: Chrysler B and RB series big block engines

Multi-Layer Steel Technology:

Cometic's MLS gaskets feature multiple layers of stainless steel with a Viton rubber coating, providing superior sealing capabilities and exceptional durability. The MLS design allows for controlled compression and expansion during engine operation, accommodating thermal expansion and cylinder head movement. This construction makes them ideal for high-performance, turbocharged, supercharged, and high-compression applications where traditional composite gaskets may fail.

Benefits:

• Excellent resistance to combustion pressure and temperature extremes
• Reusable design with proper handling and installation
• Superior conformability to sealing surfaces
• Reduces gasket failure in demanding applications
• Maintains consistent clamping pressure across the entire sealing surface

The siamese bore configuration provides additional support between cylinders, making this gasket particularly well-suited for stroker engines and high-horsepower builds. Proper surface preparation and torque specifications are essential for optimal performance with MLS gaskets.
