stupid beginer question

Hi everyone. I'm new to this forum and new to lifted vehicles all together.  I bought a lifted cherokee a while ago and was told it has a 3 inch lift on it. It has 35s and a decent amount of clearence. In the back but not so much up front. I need to find springs that'll even the lift out. There's already 2 inch coil spacers up front which id like to get rid of.  I'm not sure of the size springs I should get. I was told the stock shackles are 3.25 inches long not sure if its true or not, my shackles are 9 1/2 inches long bolt to bolt with 4 leafs stacked and 2 inch blocks between them and the rear.  I have no clue on how to come up with what size the lift is actually. I was thinking about 8 inch lift springs up front to try to even it out plus ill have the spacers if worse comes to worse and its a little uneven. Also not sure on the weight difference but the jeep will be running a ford 351 cleveland or modified with a c6 tranny(not sure which I want to use yet) does anyone know an estimate on the size springs I should get for up front?  Thanks in advance and sorry its a stupid question and I realize it'll be hard for you guys to tell from just describing it.  

And if the 8 is too much I'm willing to jack the rear end up a little too.  

man im not real clear on what youre trying to do but, i will tell you, you cant just add taller springs. the geometry changes and they dont act right. get with a supplier and see what they have, speciffic to your rig.
