Yep looks like a stroker piston based on the EJ25D (like the wiseco stroker), 2mm for the difference in stroke and 1mm for thr difference in the rod length.

Unless you wanted to change the deck clearance on purpose as part of your CR adjustment the compression height should be the same as the stock piston.
