Heard a guy at the parts counter in Tulsa say he reuses head bolts "all the time" and it's been bugging me for a week
He was buying a gasket kit for a 6.0 and laughing about how torque-to-yield bolts are "a scam by the fastener companies." Those bolts stretch past their yield point when you torque them, so they will not clamp right the second time, and I have seen a head lift at 40k miles because of it. Has anyone actually caught a comeback job from reused TTY bolts, or am I overthinking this one?
