340 exhaust manifold studs leaks coolant

I just drained a little coolant from the radiator and pulled off one of the studs to let pressure out. That worked well. The driver side I'll try the double nut lock and try to remove the two wet studs keeping the manifold on. Their not tight so I think that will work. Not much room on the driver side I have power brakes. Thank guys and Have a Great New Year.
