Main bearing size understanding?

So my 302 block was line bored, and my crankshaft was turned 10/10. Both main journals and rod journals.

So when I go to order my main bearings do I order them

-.010 size
+.010 size

Also noticed that I couldn't find -.010 in rod bearings. They always list as +.010

Sorry for being such a noob at this. This is my first full engine rebuild and I'm reading up on everything and asking what I can to get this thing built right.

I read everywhere about this undersized and oversized stuff and everyone seems to be confused about it. Of course I am going to use plastiguage and make sure it's right once it's in, but I just want to make sure my understanding is correct.

Thank You!
