Engineered specifically for 2011 through 2026 Ford F-250, F-350, F-450, and F-550 Super Duty trucks (as well as F-600, F-650, and F-750 commercial chassis) powered by the 6.7L Powerstroke V8 turbo diesel engine, the Genuine Ford Cylinder Head Bolt (Part # BC3Z-6065-B) provides exact factory replacement hardware for engine rebuilds, valve train service, or cylinder head gasket replacement. In standard-output stock engine builds undergoing routine maintenance where aftermarket head studs are not required, retaining factory fastener geometry ensures reliable factory-spec clamp load.

The 6.7L Powerstroke cylinder head architecture relies on factory torque-to-yield (TTY) fasteners designed to stretch a controlled amount during final angular tightening, locking the cylinder head securely against the multi-layer steel (MLS) head gasket and engine block. Because factory TTY bolts experience permanent plastic deformation upon initial torquing, reusing old factory head bolts during engine reassembly is strictly prohibited and risks immediate gasket blow-out or fastener snapping. Sourced directly through Ford Motor Company, part number BC3Z-6065-B delivers precise metallurgical integrity, correct thread pitch, and factory heat-treatment specifications with zero core charge.

Key Features & Benefits

• Genuine Ford OEM / Motorcraft Quality: Manufactured to strict Ford engineering standards for precise thread engagement, tensile strength, and clamp load retention.
• Exact Factory Torque-to-Yield (TTY) Design: Engineered to stretch uniformly during angular torque sequences, maintaining constant sealing pressure across the MLS head gasket.
• Precision M12 x 1.75 Dimensions: Manufactured to exact factory length and thread pitch for seamless, bind-free threading into the engine block blind holes.
• Factory Knurled Shank Design: Features correct factory shank formatting and head markings for proper block alignment and fastener identification.
• Zero Core Charge: Brand-new outright OEM hardware requiring no core deposit, no core return shipping, and no core inspection delays.

• Quantity Warning: Note that these head bolts are sold individually. A complete 6.7L Powerstroke V8 engine requires a total of 18 bolts (9 per cylinder head). Ensure you order a quantity of 18 for a complete engine overhaul.
• Block Hole Preparation Tip: Thoroughly clean and tap every threaded blind hole in the engine block using an M12 x 1.75 thread chaser. Remove all oil, coolant, carbon, and debris. Blow out each bore completely with compressed air—fluid or debris trapped at the bottom of a blind hole will cause false torque readings or crack the engine block casting when the bolt bottoms out.
• Installation Tip: Lightly lubricate clean bolt threads and underhead bearing surfaces with clean engine oil or factory-specified assembly lubricant before installation. Follow Ford's multi-step torque-angle sequence precisely (torque to initial spec, then turn specified degrees in angular rotation). Do not reuse old head bolts under any circumstances.
