B - id give it a torque before a new gasket. Cant loose anything but a few hrs. Its worked for me several times. Think spec was 60-62 lbs with iron head and steel nuts. Dont just pull them up but break them loose first then bring them up otherwise ur pulling against hardened old junk on the threads and u get a bad reading. Between the old threads in the block, old studs that stretch and have old threads, a gasket that likes to compress and if old nuts were used, i find u have to torque many times and even then ive lost torque a few yrs down the road.

When u brought that new car into the dealer back in 1940 for that 500 mile - 1,000 mile - or checkup, thats one of the things they did RETORQUE THE HEAD.
