Default What should compression test read?

I tested the suspect 85-L98 engine(cold, cant reach in there with it hot :cry )

Went through 4 complete stroke cycles with the meter in. All hit over 100 psi on first and all got to over 150 psi by the 4th. At this point do I say Rings, Heads, valves, and gaskets are fine and not worry any more???

Thanks

(thought I'd be more specific in my posts) :D

FWIW, mine are all in the range 160-180. They are all supposed to be within 10% of each other. I have never heard what's ususal for an L98.
