Cylinder head bolt is the connecting part to fasten cylinder head and cylinder block. Its distribution position has a direct impact on the stress condition of cylinder head and cylinder block, sealing reliability and deformation of cylinder sleeve. In order to ensure a good sealing of the joint surface, the cylinder head bolts are required to have a certain preload. However, too much preload will cause fatigue damage to the bolts and warpage and deformation of the cylinder head, resulting in air leakage, water leakage and even damage to the cylinder gasket.
Greater Clearance Around the Bolt Head for Tight Places
Will Not Rust like OEM or ARP Black Oxide Fasteners
Ensure that the cylinder has a good seal and will not damage the cylinder head
Stainless steel allen socket head bolts will not round off like hex head bolts and are the clear choice when bolt clearance and accessibility is at a premium.

Use a hex wrench to loosen and remove the cylinder head bolts in a diagonal sequence from both sides to the middle.
Use a plastic hammer to tap the rib part of the cylinder head to remove the cylinder head, and place the cylinder head on the wood block of the workbench.
Align the cylinder head with the locating pin of the cylinder block, and then level it. Use a hexagon wrench to loosen 10 cylinder head bolts in the diagonal sequence from the middle to both sides (the reverse of the removal sequence)
Cylinder Head Bolt
We do our best to assemble kits that fit as many parts combinations as possible.
Due to variances in gasket thickness and the parts being assembled, we always recommend that you measure the thickness of your gasket and accessory flange and double check that the specified size will work for your application.
