While true an intermittent or low reading might be fixed by retightening the gauge nuts, a high one won't. It sure is possible the gauge regulator is stuck, if it is the old mechanical type that works by heating a bimetal contact. To see if the regulator is working, turn the ignition on, pull the yellow wire off of the gauge sender on the head and measure the voltage at the wire's terminal. If a steady 10V, you have the new solid state replacement version (looks the same as CB mentioned) but if you have a pulsing battery level voltage, you are watching the mechanical regulator do its thing. If you have full battery voltage and it is not pulsing, your regulator, mech or otherwise, is stuck, making both gauges read too high.
