BBM Head Gasket

The BBM Head Gasket (FEL1105) is a precision cylinder head gasket designed for Mopar B and RB-series engine blocks. This essential component prevents combustion gas and coolant leakage between the cylinder head and engine block, ensuring engine reliability and performance. Ideal for those rebuilding classic Mopar muscle cars or restoring heavy-duty truck engines, this gasket is a vital part of any engine overhaul.

Constructed with a steel core laminate, this head gasket is engineered to withstand high combustion pressures and thermal cycling without degradation. The steel core reinforcement helps prevent gasket creep and blowout under extreme engine loads, while the laminate layers ensure consistent sealing across the combustion chamber. Proper installation requires careful surface preparation of both the block and head decks, along with correct torque sequencing according to engine specifications.

Engine rebuilders, performance enthusiasts, and restoration shops can rely on this gasket for compatibility with Mopar B-block (340, 360) and RB-block (383, 400, 440) engines. Its design supports a uniform seal that maintains cylinder pressure and prevents coolant bypass, making it an economical choice for complete engine overhauls where fitment and reliability are crucial.
