13:1 should be fine, maybe up to 13.5.
You should check if squish band is parallel or tapered and correct to parallel. Can't remember thought the 200 wasn't bad in that respect but different piston manufacturers may be different as may changes over the years.

On my '15 200, I found the OEM base gasket to be 1mm. The OEM volume above the piston is 15.2 - 15.5 ml (measured twice, got different results) which should give a CR of around 14:1. So I will aim for unaltered CR as this works well with my fuel.
