Head Bolt Set (1-Head)

The FEL-PRO Cylinder Head Bolt Set (ES 72856) is a precision engine fastening kit engineered for small block Chevy applications. This hex head bolt set delivers the clamping force and dimensional consistency required to maintain proper cylinder head sealing, critical for preserving compression, preventing coolant weeping, and ensuring long-term engine durability under demanding operating conditions.

FEL-PRO is recognized in the automotive rebuild and performance community for OEM-grade fastening specifications and material consistency. This cylinder head bolt kit uses steel construction with natural finish, designed to specification for small block Chevy engines requiring precision head bolts. The kit format ensures all fasteners are matched for consistent torque characteristics and proper load distribution across the head gasket sealing surface—a critical factor in rebuilds where uneven clamping can lead to gasket failure and internal leaks.

This set suits engine builders, restoration shops, and serious enthusiasts performing cylinder head work on small block Chevy platforms. Whether executing a complete engine rebuild, replacing a failed head gasket, or upgrading to a performance cylinder head, proper fastening hardware is non-negotiable—undersized or mismatched bolts introduce risk of head lift, coolant loss, and catastrophic engine damage. The FEL-PRO hex head design ensures straightforward installation with standard socket tooling and allows for precise torque sequencing during head assembly.

Small block Chevy applications span decades and multiple displacement variants—correct fastening hardware is foundational to any build's integrity. This bolt set is engineered to OEM specifications, making it the baseline choice for quality-conscious builders and shops where repeat performance and warranty confidence are essential.
