Default need help! anyone who knows about compression!

ok so i am looking at this c5 zo6. it has a procharger on it and a 100 shot of nitrous. it is a direct port system. the car has 29k i think maybe 4k miles less. but any way the car was biult right using top dollar everything. i mean everything. it from teh original owner as well. its a bad *** car but when he got the compression checked it read this

left bank
147,145,145,145
right bank
145,147,145,145

and idk what that really means im not going to lie. i jut know its better for all the numbers to be the same lol... but anyway i was curious does this mean anything about reliability? would the car be safe to drive 2000 miles, yes two thousand, back to my house. which is what i planned on doing.

Are you sure about those numbers? They look nice an even, but I have seen numbers usually around 185-190. Not sure since I have never done one on my car!

numbers look great. If you test it tomorrow you Will have dif readings, if the engine has a dif temperature. The most importing thing is that they are as equal as possible. And they are good. Ready to go man.

I would look a little deeper for some possible specs those numbers do seem a little low,unless the engine has aftermarket heads to drop compression for the charger.

I think those numbers look really good. Being in the 140's I would suspect some low compression.
