sounds low, but consistent numbers are a plus.
I think FSM calls for atleast 128 as long as they are all close together. You may have a thicker head gasket or something else lowering the readings.

120 is def low. The stock compression numbers in my L28 are 147psi and that's with a 7.6:1 Compression ratio.
HOWEVER the guage you are using could be incorrect. The fact that they were 120 all the way across is a good sign. I would try another guage to be sure.
