That isn't exactly correct. The torque-to-degree specs in the FSM ONLY apply to the stock bolts because they are torque-to-yield, which is why you cant reuse them. If you were referring to stock, then yes, you must reach the required degree setting or the bolts will be waay undertightened. Once you have reached the required torque on the studs as per ARP, you are done.
