Default good compression?

so here are the compression numbers from the test i did the other day..
comp at first crank/ comp at 5th
1-150/180 psi
2-150/185
3-130/185
4 -125/180
5 -125/185
6 -125/185
7 -125/185
8 -125/180

this seems to indicate there has been some work done on the engine before i got the car... anyone else think these are kinda high?

Who cares? With compression like that, you're good to go.
