Why 11.8-12.25 pistons?

Hi, why Wiseco writes that pistons are 11.8-12.25CR? I have ITR with OEM headgasket - so will I have 11.8 or 12.0 or 12.25?

Re: (itr_18)

maybe they give the CR a range instead of one figure because some people will be using them with a b16 head and some will be using them with a gsr head, or even an LS head, and the combustion chambers are of different sizes, so instead of saying that it would be 11.8 with a GSR head and 12.25 with a b16 or itr head, they just say 11.8-12.25.
