CG/CGA cylinder wall thickness

Is there any difference between CG and CGA cylinder wall thickness? CG has 71mm bore and CGA has 72mm bore. I just want to know is the cylinder wall thickness same between them or has CGA thicker wall? Because if it has, then it's an better option for oversize pistons. But if they have same outer cylinder diameter, then it's just as safe to drill CGs bore bigger.
