Testing compression

Hi all, what figures should I expect on a compression gauge (psi) when testing a freshly rebuilt standard comp engine?

Just wanna make sure everythings OK.

As even numbers as possible. The value itself depends greatly on the cam. On a standard cam around 10 bar (147psi) is common. A bit less with a hot cam.
