My old sr block had almost the same scratches. I always use 3 coats of coper spray on my HG and never had any fluid or comperssion leakage. The head is a different story as its right in the compression area and any sharp little booger sticking out could cause detonation. I would think a machine shop could smooth those out no problem.
