This sounds like it is more importantly a school project than a built motor. Because if all the motor needed was a little carb work, it don't need rebuilding. Not for what you want. When you get the cam, don't go to big for those heads you got. Which those heads do suck ass. Just make sure you get a timing chain that matches the cam. If you are unsure, just ask the jeg's guy. The main thing about the cam is you can't run much duration and lift with those heads. You will need some valve springs if you much over a .470 lift. Does this motor not already have a distributor? Any early 70's-84 dist will work. Even if it is points. But try to stay electronic if you can. It is much better. The main thing about the 351 heads was the slightly larger ports and larger valves. You can do this, but you will need some head bolt bushings. The 351 uses 1/2" head bolts and the 302 uses 7/16". As far as pistons and rings, you will need to tear down the motor first. You never know how well the previous owner took care of the motor. This also depends on whether the crank needs grinding. If you get down into this motor and it needs to be bored and the crank ground, you are looking at a $140+ in machine work. The guy who sold it to you might have said it was still standard bore. But what if you take the heads off only to find out that it is already bored .060? That would suck. Don't order any parts until you know what you need. If you order .030 over pistons, you would need .030 over rings to go with it. And for a novice like you, don't get file fit rings. Most standard replacement pistons have 5/64, 5/64, and 3/16 ring grooves. Racing pistons would have 1/16 ring grooves. And those 1/16 rings cost more too.
Btw, I just looked in summit's book. There is rebuild kit for 68-82 302's for $249.99. Comes with everything you need. Except for the cam and lifters.
I hope this has shed some light for you and not confused you.

Thats what I said about the kit.. get the kit which will have all you need.. I guess where trying to go Power here and I know when i was a kid which wasn't long ago and wait acually I still am, HA, its all about getting it running. if thats the car in the pic that your doing this all to, then save the car, save your money and get a real motor and restore that car.. it looks great so far.
