Cylinder Bore Scratches Opinion

[Moore]

Looking for the opinion of someone who may have built a couple motors.

Here are the pictures. I did not see these scratches until I got the block back from the machine shop.




You can see a couple small scratches, these are in cylinder 3 only. I can lightly catch a finger nail on 2 of them, they are not very long but would likely touch the top compression ring. The shop took measurements, cleaned and deglazed the cylinder. The guy is telling me that the scratches were present before they worked on it, but in his opinion he did not think boring was required and if it was his own motor he would have done the same. Of course he's telling me if I am concerned bring it back and they will bored it out. The other pia part is I already purchased piston's to stock size when he told me the bore checked out okay. So should I spend the money to get it bored and deal with trying to return/exchange the pistons or leave it be?
