440 restoration for my Dart

I found a 440 4-barrel in a GTX 1970, and i want to make a good restoration of this engine. I am looking for a set of pistons in 0.20, but i dont know which are the best for my restoration project. Because i dont want to loose the 375 hp....
The camshaft is in bad conditions, i think this MP 4452783 is the resto part...am i correct or no?.
