question about compressed spring height

i was wondering on the front end of jeep cherokees the height of RE, TeraFlex, or Rusty's Offroads lift coils are at the compressed height ( on the ground with winch bumber ), i was wondering so i would know the finshed heighth from the get go instead of buying different height springs to get the right lift i want to achieve. what are the BIGGEST front coil springs u can get for an Xj? whats the price on them? hows the flex? what is their compressed heighth? where can u get these? i'm lookin for AT LEAST 8" of lift from the springs and the max would be to where the springs get me touchin the power lines ( ya right) .....the answers would really help out
thanks

Rusty's 9.5" are the tallest i know of but they tend to bow a lot over 6".
