For what? Without knowing, I will give you the head bolt specs. First, always use new bolts. Begin in the middle. Then go to the ends. Never tighten two bolts on the same side in sequence.. First torque them to 22ftlbs, the go around and do them again give them 1/4 turn. 90 degrees. Then do that AGAIN, go around the sequence a third time and give them another 1/4 turn. Toyota provides no specifications for the final ftlbs of torque.
