They are within 10% but a bit low the lower compression ratio might be the cause. What ratio you running?

all engines will have an increase when oil is put down the bores but +20psi of yours I would say yours are pretty much on the limit.
Was it up to temp, throttle open etc?

I'd be content with those readings. As said, oil does slightly raise the compression ratio.
9:1 - 9x14.7= 132psi ideal compression.
