Just pulled my /6......Now I need some answers

Just pulled my /6 out of my 1970 dart. My dad is giving me his 360 out of a 77 power wagon with 110k on it. So question is.....do I rebuild the 360 or just re-gasket with out heads off and put it in or rebuild it. I am trying to make this a daily driver and have my wife drive it also. Second question.....904 or 727. The 360 has a street cam and dual plane intake...what's your guy's opinion?
