Please advise what the compression readings for a 1948 Pontiac 8 cyl Streamliner should be.

Thanks, again

Just turned 52,000 which I know are original since my father bought it in 1950. Also, the engine was rebuilt in 2014 at 49,399 miles. Oil pressure is good.

2 cylinders are at 110, 5 are at 120, and 1 is at 95 & 100 wet. Is that indicative of an issue?
