Put a head gasket,TCC and chain on. My mechanic torqued the head down to 70 ft/lbs. I chased the block threads and put 10/40 on the threads of the bolts before I put them in. The truck started and we let it run for about 15 minutes. I drove it the next day for about 5 miles. i finally got a torque wrench and went to retorque the head bolts, 3 of the needed tightening. One wasa little more than a quarter turn, one was less than a quarter, and the other one was less. Should I retorque the bolts after 50 miles or check them once a week until they stay torqued? some of the guys who have rebuilt and os put head gaskets on I would appreciate your opinion Thank you
