Yes, you can RTV the new gaskets in. (I always do as the OEM specifices too little pressure on the valve cover bolts to start with, but being aluminum threads, the steel bolts easily strip out with enough pressure to seal the entire gasket surface instead of the tiny raised strip)
Make sure the mating surfaces have been completely cleaned of oil.
