Do not know if it will cause gasket problems or warping of the head. During re-torque, or loosening the head nut, it is recommended to drain coolant so the coolant level is below the head. Done to prevent seepage/leaks while the head is not properly torqued.

As Mike posts, do it as quickly as you can.

After a couple of thermal cycles, and some miles perhaps do an additional re-torque on the head to play things safe.
