How do these compression #'s look?

I did 5 cylinders and got the following #'s.

cyl first turn 3-4 turns of motor
1 118psi 154psi
3 115 150
5 112 162
7 112 151
8 118 151

Got bored and didn't feel like doing the rest, but these #'s seem to be pretty good for an 152k motor that has been sprayed and cammed.

So long as your #'s are within 8-10%, i wouldnt worry too much...
