If they are softer, muddy stones then this won't be a problem and you can use them as is, sharpening will take down the marks in a hurry. If they are harder stones then you might have to buy a nagura of some time to remove the gouges. But most nagura aren't really good at lapping (too small/slow), so you'll definitely have to start with the DMT. When I did the initial flattening of my natural finisher I lapped with DMT, then lapped with my other flattened stones in order (500, 1000, 6000), progressively removing the marks till I got to the tomonagura. Worked well for me.
