Hey everybody, New to mopars so far I'm liking it

I recently acquired a 1977 LA 360 block and discovered this in one of the lifter bores. Some one please tell me it's no big deal PLEASE!!!! I was planning on building a stroker out of it but I think I'm screwed with block. paid $300 for it. My guess is it's hashed.
