I have diamond dished pistons with valve reliefs. I have a boosted motor and am only running 8.7-8.8:1 compression. So I want to say they are 16-17cc dished pistons.
here is a pic of them waiting to be installed

Those look identical to my pistons. Mine are 17cc dished with valve reliefs. I like the coating options you have. Ive also thought about swapping out my pistons for a lower compression set with a top coating. Im just not sure if I want to tear that far in to my engine when I had it built just a few years ago. I was told my set up is 9.2 to 1 compression still.
