Default CP 12.5 Pistons but which one???

I was planning on running OEM B16 pistons in order to raise my compression on my LSVtec but ive decided to go higher 12.5 and have been looking on CP's website but they have two types i guess regular and x style forged.

i believe there was some conflict between CTR pistons and a GSR head as far as clearance
