MY compression test results. What do they mean?

Hi, I did a compression test on my girl friends 87 NA and these are the results I got.

cylinder 1-3: 180 PSI
cylinder 4: 190 PSI
cylinder 5: 180 PSI
cylinder 6: 210 PSI

This is really high conpared to what the repair manual says its suppost to be. I think it said it should be in the area of 120 or so PSI. Whats wrong?

The car seems to be in horrible condition, so me and my friend are just trying to figure out whats wrong so we can decide if its worth fixing up or not.

Thanks for any help.
