Depending on your budget...it does not matter if they are drilled-as long as thickness is within specs, you are OK to resurface.
I'd take old rotors to resurfacing place and ask them to put them to lathe to see if they are actually warped. Once I had "bent" rotor-where it sits on the hub, not on the friction surface. (I tracked the car, but still have no clue how it can happen)
Otherwise-get new rotors-try different brand, make sure hubs are shiny clean before install and NO impact gun on wheel nuts, manual torguing only.
Regarding heat-unless you are tracking, you should not worry.
