Fel-Pro ES72229 Head Bolt Set
This Fel-Pro head bolt set is engineered for automotive engine repair and rebuild projects. It provides the critical fasteners required to secure the cylinder head to the engine block with proper clamping force. Professional mechanics and experienced DIY enthusiasts use this kit during major engine service.
Sustained clamping performance
The bolts are manufactured to maintain consistent torque retention under the extreme thermal cycling and combustion pressures found in modern engines. They resist the relaxation that can occur during repeated heat-soak and cool-down cycles. This behaviour helps preserve head gasket sealing integrity over the full service interval.
Torque-to-yield application limits
Many current engines require torque-to-yield bolts that stretch permanently during installation and cannot be reused safely. This set supplies new bolts meeting the correct yield specification for the application. Builders must verify the specific engine service procedure before installation to ensure the correct tightening sequence and angle are followed.

Questions about this item
How much heat does the Fel-Pro ES72229 head bolt set generate during extended engine operation?
The bolt set itself produces no heat; it simply clamps the cylinder head to the block while the engine creates its own thermal load.
Which torque wrench and socket sizes must I already own to install the Fel-Pro ES72229 head bolt set correctly?
You need a calibrated torque wrench and the correct socket for the bolt heads; the exact drive size and socket dimension depend on the engine being serviced.
Will the Fel-Pro ES72229 head bolt set work with the original cylinder-head bolts still in my engine?
No, head bolts are typically torque-to-yield fasteners that must be replaced; reuse of the original bolts is not recommended.
