440 rebuild need help

I have a bone stock 440 from 4-7-68 this motor had never been taken apart its seized up but only by the rings the rest of the motor looks nice even bearings and cam lifters all is well inside the motor what I need to know is what rings cam bearings do I need can I reuse them they have no scarring whatsoever and the cylinders just need to be honed no pitting anywhere I might go with a aftermarket cam but I can handle that myself. Any help on this will be appreciated im not that experienced and what I do know has always been on my little 318 and 360's. Also seems to have 413 heads on it? I was told before 413 heads wont fit on a 440. Is this true?
