what color locktite for intake studs

I picked up a used eddy air gap and am going to use studs for the carb and thermostat housing. I read to locktite them in so they don`t come out when I want to make changes. Is the blue good enough? I am a little scared to use red as I hate to f up the threads later if the studs do need to come out. Any advice or opinions out there?
Thanks Mike
