If you're replacing the bolt then you can use those torque specs (59 ft/lb + 180°) but if you're reusing the bolt then typically you'll give it a grunt or two with some blue loctite as mentioned.

If you do the 59 ft/lb + 180° on a used bolt you may stretch the bolt even more and risk snapping it (bolts stretch when torqued past a certain point, and stretching them again will put them even closer to snapping). TTY bolts are used to make sure a bolt goes on as tight as it needs to; if there is rust in the threads, for example, going to 80 ft/lb or whatever may not make the bolt as tight as it needs to be, but doing 59 ft/lb then 180° makes sure it's tight, no matter the resistance.
