FEL-PRO ES 72856 Head Bolt Set (Pack of 2) - Engine-Grade Fit

Our review of the FEL-PRO ES 72856 Head Bolt Set (Pack of 2) finds it most suitable for technicians and DIYers replacing cylinder head fasteners who want a direct, application-specific replacement that meets factory standards. These kits are validated for fit, form and function and come cold-formed and heat-treated to preserve strength, which is the single biggest reason to choose them: they are made to avoid the risks of re-using torque-to-yield fasteners and to deliver reliable clamping during head re-torque procedures.

Key Features

• Per-pack contents: Each pack contains two head bolts and hardened washers, giving a complete set for the specified application in this kit.
• OE specification: The bolts meet or exceed original equipment specifications to ensure a proper match for replacement use.
• Application-specific design: Bolts are tailored to fit specific vehicle and cylinder head applications, reducing the risk of misfit during installation.
• Manufacturing process: Cold-formed, heat-treated, thread-rolled and machined construction preserves molecular integrity for consistent strength and durability.
• Reduced head profile: Reduced-diameter bolt heads help avoid valvetrain removal and make future cylinder head re-torquing easier.
• Validated performance: Each kit is validated for fit, form and function so installers can rely on predictable results when following manufacturer procedures.

Who It's For

This head bolt set is aimed at automotive professionals and informed DIY mechanics performing head gasket service or cylinder head removal where original torque-to-yield bolts must not be reused. The kit suits those who prioritize a correct fit and proven tensile properties without fabricating or modifying fasteners.

It is not intended for users who need a bulk supply for multiple engines or for applications outside the specific vehicle fitment indicated by the manufacturer; in those cases a full kit sized for that engine or factory-specified fasteners should be selected instead.

Pros & Cons

Pros

• High manufacturing quality from cold-forming and heat treatment provides dependable strength and reduced risk of breakage during installation.
• Includes hardened washers and comes with thread sealant applied on many installations, simplifying assembly and improving sealing.
• Reduced-diameter heads allow re-torque without valvetrain removal, saving labor time on service jobs.
• Validated for fit, form and function so installers can match factory replacement procedures closely.

Cons

• Sold as a pack of two for specific applications, so buyers must confirm the correct kit rather than expect a full multi-bolt engine set.
• Some reports mention mixed impressions of bolt strength in certain heavy-duty scenarios, so follow torque specs and replacement procedures closely.
