Broken Valve Spring

Hey guys, I have a quickie question, Today my intake valve spring, in my 340, for my # 7 cylinder collapsed and is now in pieces so my question is can this spring be replaced without tearing off the head? With todays technology I was thinking that their is a way but if I have to tear it down then so be it. I dont want to start tearing it down only to come and find out that it could be replace while still in the car...
