to rebuild or just lower end 71 440

I have a 71 440 that was build 20 yrs ago had low on start up, decided to go a different route...engine have been stored inside this whole time...took just the pan off and crank out seen it had a few hole in the crank that a few pices of thin rubber in them, and the bearing had some scratches, so I got the crank turned and new bearings...do I take it all the way down, or just the crank and new bearings...
