With the introduction of "torque-to yield" head bolts in the early '90s, replacing head bolts whenever a new head gasket is installed, changed from being a "good practice" to a "necessity" because factory-installed bolts were intentionally stretched beyond the point of permanent distortion. Magnum continues to recommend more strongly than ever that conventional head bolts be replaced on pre-1990 engines because of the extensive corrosion, wear and re-use they have experienced in many years of service.
Each Magnum box contains all the bolts, and washers if required, to service one cylinder head. This often includes two or more sizes of head bolts, as dictated by the engine design.
