  • Long Stud and Head Bolt Torque Settings

    Hi guys,

    I'm looking to confirm the torque settings for a block / head with 6 long studs and 4 standard stretch bolts across the ends. I've seen two recommended settings as follows:

    1. 30lb, then 60lb, then 90lb on all 10 studs / bolts.

    2. Do 30lbs, 60lbs, then 90lbs on the long studs. For the four stretch bolts, torque up to 25nm (18lb), 45nm (33lb) and then 180 degrees. This is the recommended settings from Ford for the stretch bolts.

    Option 1 seems better to me as all will be torqued to the same setting. However, I'm mindful that the torque settings for the stretch bolts in option 1 seem considerably higher than what Ford recommend for the stretch bolts. Is this a concern from point of view of potential over torquing causing bolt failure?

    Cheers,

    Rich
