Compression Tests

So im looking for either a 5.3 or 6.0 for my monte and have been searching on car-parts.com for the most part. Alot of places have the compression listed but im not sure what the proper "value" should be. So if anyone could chime in and let me know.

Ive found a 2001 6.0 with 80k for a good price and compression is listed at 175, is that good or will it need fixed?

On my 5.7, I got between 180 and 185 so on a truck engine with slightly less compression, I would think 175 would be perfect.
