Keep in mind all 4 on each side are consistent. One side is 150-160 and the other side is 185-200 PSI. Usually when you have a damaged cylinder or gasket, two adjacent cylinders are really low and the others are much higher. A damaged set of rings shows high leakdown and compression numbers in that hole only. The other cylinders are usually consistent and higher. Even a nitrous type failure only kills a hole or two unless it throws parts into the grandstands.
Having one side consistently at 150 and the other side at 190 is not cylinder sealing, usually. Its always possible something went through one side of a motor or the drunk uncle built one side, but that's a weird one-off.
I still say confirm the leakdown then pull the heads.
