Not sure if it helps any, but mine's bored .020" over, and I don't think there was much of a difference between that and stock size. Of course, I can't really tell that well, because I raised the compression to 9.5:1 as well as fully rebuilt and balanced the motor.
So, unless you're planning on changing to a set of aftermarket pistons and doing a full rebuild, I don't think it's worth it just for the slightly increased displacement.
