NEED HELP, b18b1 stock compression per cylinder PSI

I purchased a 1994 Integra b18b1 from an auto integra. $600 with auto ECU. They told me the compression 1,2,3,4 is 150/160/150/160 … I think that is low. I think they did not do a compression test. I did the math of 9.2:1 times 14.7psi, and it equals 132. so any advice here?
