Kohler (Parts Bulletin 257) has determined that it is no longer necessary to replace the head bolts each time the head is removed. However, it is important that the bolt/stud threads be lubricated with engine oil prior to each installation for consistent tightening/torque characteristics. The oiling instructions are part of the installation instructions in each kit. For engines that use studs, washers, and nuts to mount the head, it is still recommended that the nuts and washers be replaced each time the head is removed. The replacement nuts and washers will remain in the gasket service kits, but new bolts will no longer be provided.
