Default Compression w/pr3's and stage 2 cams?

ok, just had a thought. what is the compression for an ls/vtec with a set of pr3 or p30's? stock bore block and the head is not milled. i know it's supposed to be somewhere in the range of 11.3-11.5, correct? i am possibly looking into the skunk2 stage 2's or either the rocket m22 or m23's. will the m23's be too much lift/duration for the cr? not sure yet which i am leaning towards.

pr3's are similar to jdm itr pistons which put you at about 11.7 cr in an lsvtec with b16 head
