2lt block boring??

Just a question?? i have a 2lt block and top piston has picked up so needs boring out. How do i stand with over sizing only one pot???
I have built engines before but always bored all pots as it was needed. on this block all the other pots are spot on just the top one??

Is it done or should i do all anyway??
Thanks
Matt

Can you acid wash it and give it a hone? The XR2 bores are quite durable. You would be surprised what a bit of careful work can do.
