SUMMARY
The discussion centers on the torqueing and retorquing of bolts, particularly in the context of head gaskets and fasteners. It is established that while modern head gaskets typically do not require retorquing, older composite gaskets may have necessitated this practice due to settling. Factors such as material deformation, dirt in threads, and the distinction between bolts and screws are also highlighted. Ultimately, the consensus is that if the initial installation is done correctly, the markings on the bolt and surface should align upon refastening, provided the materials do not undergo permanent deformation.
