I was just assuming. I've never seen a stock 370Z piston. Higher CR can also be accomplished with cylinder head bowl volume, piston crown design, rod length, shorter deck height, etc.
I'm probably wrong assuming that; most newer low-emissions engine designs utilize thin top ring lands and tighter ring gaps (bad combination) for emissions reasons.
