E-Series Head Bolt Kit BBM 440

The E-Series Head Bolt Kit BBM 440 is a precision fastener assembly engineered for high-performance cylinder head applications on Mopar B and RB-Series engines. This kit exists to provide operators and engine builders with OEM-grade fasteners that maintain critical clamp load and head gasket sealing integrity under extreme combustion pressures and thermal cycling. Whether you're rebuilding a stock engine or assembling a modified performance platform, proper head bolts are non-negotiable for reliability and longevity.

Manufactured from chromoly steel and finished in black oxide, the E-Series Head Bolt Kit BBM 440 delivers superior tensile strength and corrosion resistance compared to standard zinc-plated fasteners. The hex head design allows for precise torque application using conventional socket tools, ensuring accurate preload distribution across all cylinder head mounting points. Black oxide coating protects against rust and provides a professional appearance while reducing reflectivity—a consideration for field-stripped powerplants. Chromoly construction resists stress relaxation and fatigue, critical properties when head bolts experience millions of thermal expansion cycles at operating temperature.

Engine builders, restoration specialists, and performance technicians benefit most from this kit's consistency and durability. The E-Series Head Bolt Kit BBM 440 is purpose-designed for Edelbrock cylinder heads paired with Mopar B and RB-Series engine blocks—verify your head casting and block combination before ordering. Installation requires a torque wrench calibrated to manufacturer specifications and adherence to proper bolt sequence to achieve even clamping force. The complete kit eliminates the need to source individual fasteners, reducing assembly time and ensuring matched metallurgy across all fastening points.
