What you have is most likely a 30 over 350. The pistons are generally a few thousandths smaller than the bore. The rings maintain the seal between the cylinder and piston. Most oversized pistons are stamped with the size.
I would take the block to a machine shop and have them check it. .010 difference between cylinders seems like way to much of a difference.
