Default Retoqueing head bolts

After the heat cycle ( just curious ) with Engine cold what procedure do you use to retorque Heads. Do you back off 1/4 turn then torque back up to spec’s Or do you just go around retorque.

I’ve heard guys doing this way.

I have always just re torqued without backing off. This is using ARP lube on the nuts and washers. Also on both aluminum and iron heads.
No problems past 30 years.

When the motor is fresh (New) after we make 3 or 4 runs we re-torque

The proper procedure is to do one bolt at a time. Back them off 1/4 or so and then torque to spec in one continuous pull. If you don't back them off the breakaway torque may be more than the reading. Then you are doing nothing.

The proper procedure is to use a 1980's American made torque wrench that has always been able to hold its calibration and not the Chinese mass produced crap that is being sold these days.
