How did your chain fail? Did it jump time or the chain snap? Did it happen while driving or at idle? Old turkey is right that the 2.4l im assuming you have is an interference engine. Depending on how it failed or if its just on its way to failing like a stretched chain, that will determine next steps. If it hasn't actually jumped time and is just stretched and slapping or has a cold start rattle, then you dont need to worry about internal engine damage and can just do the timing job. If it completely failed and timing jumped or chain broke, then you need engine internals inspected because you likely have damaged valves.
