    Do these 3.5 engines have torque to yield head bolts?

    ^FSM shows they're re-usable, so not torque to yield

    Yes they are TTY (27 ft-lbs + 90 degrees + 90 degrees), FSM states they can be re-used if they meet specs.

    If your at the point of tearing the block apart, head bolts aren’t that expensive and worth changing out.
