Are these the same?

I was about to order cam gears on NOPI, and Skunk2's said 1.6/1.8/2.3 ltr. DOHC and they don't seem to have a text input field to specify. Are the cam gears the same size? I looked at them searching under Civic Si as my car also and they had the same model number as they did with the Prelude. Any help? Thanks.
