Default Return to Stock from CM 11 4.4

Hi everyone,

Do you know if it is possible to return back to the stock rom if I am currently on TWRM recovery running CM11 4.4 rom? All my apps keep constantly crashing and I am having issues with my text messages not going through. I found the rom for 4.2.2 but I am unsure if its possible without messing up phone. How would one even do this? Thank you again!
