Cometic C5799-051 MLS Cylinder Head Gasket for Chrysler B/RB 4.600" Bore

The Cometic C5799-051 is a multi-layer steel (MLS) cylinder head gasket engineered specifically for Chrysler B and RB big block engines. This precision gasket features a compressed thickness of .051 inches and is designed for engines with a 4.600-inch bore diameter in a siamese bore configuration.

Key Features:

• Multi-layer steel construction provides superior sealing and durability under high compression and extreme temperatures
• .051-inch compressed thickness allows for precise compression ratio tuning
• 4.600-inch bore diameter accommodates stroker and performance big block builds
• Siamese bore design for cylinder support and sealing integrity
• Engineered specifically for Chrysler B and RB engine families

Cometic MLS head gaskets are constructed with multiple layers of stainless steel, featuring embossed sealing beads that create exceptional cylinder sealing. The gaskets are coated with a Viton rubber sealing layer that provides micro-sealing properties to fill surface imperfections. This design makes them ideal for performance applications, forced induction builds, and engines running higher compression ratios where conventional composite gaskets may fail.
