Compression test

HEY ALL did a compression Test on all my cylinders. Highest i got was 150. some where diff i had 1 cylinder 115 another 120 another 120 another 125 why are they varrying my last cam was 170s???

Does this mean My valves are shot? or what do i gotta do to fix this problem

Might want to do a leak down test instead of just a compression check, works a lot better to isolate a problem.
