What do I have going on, with my front springs?
As you can see the spring is bowing out,should be straight right? If you noticed someone took out some of the tower (did this throw off geometry?), I was going to make new ones to gain 2 inches of lift but I need to bring the top out by what and inch? or how would you fix this situation, beside buying taller springs (need to gain 2 inches)

Looks to me like you are correct in your assessment. The towers have been shortened a few inches to gain lift and the way they did it caused the upper ends to be too far inboard. Not sure if that is a good idea. I guess if you want to gain another 2 inches without buying longer springs your only options are:
1. Like you said, make new towers that are 2" shorter, and 1" or so further out from the frame. (safe?)
2. Raise the lower pockets by 2". Probably a poor choice because you still have upper end to close to the frame , and you would have increased leverage on the axle, like using lift blocks (safe?)
3. Do a 2" body lift.

That would be your best bet, in my opinion.

Get a set of stock coil spring towers and drop them 2". It is very common and an easy way to gain the lift on these half tons. By the looks of your springs though they could be shot. Are those 4" lift springs or stock? I have a set of 2" leveling coils I'll sell.

You have a 460 right? Added weight and those hangers are not helping matters.
Is it possible to simply run a coil over shock? Long coils tend to de-form like this and they get worse during suspension cycles. It becomes very difficult to keep any kind of reasonable suspension repeatability when the spring is trying to pop out.
You can make a shock mount and install a coil over.
Many companies are making reasonably priced units now, and finding them used is pretty simple.
Research the amount of tension the coils have to suspend, and you can use either a dual rate or long single type.
This would be super reliable, and you will never grow out of them. They will also ride better and provide more travel.
Quite a bit more secure than that thing anyway.

I just went out there and dropped a plum-bob down from the center of the tower and it hit 1.5" from center (to the inside) of the bottom spring mount. When I make my new mounts I will adjust for the 1.5"
Now if a 460 weighs 650-750 and worse case coils are 400lbs per inch should these springs hold up to the 460? I understand things wear out. I seen some 445 lbs per inch

You might have some fun with this calculator. There is a difference between spring rate and load rate:
