There is no need to do this but if you take them for check, test each one for O/C heater.
THAT IS THE PROBLEM WE ARE TRYING TO RECTIFY. Other than that they will be O.K. They will probably read low on the tester but valve testers are not a lot of use to be honest so don't take the results too seriously. John.
