Too Agressive With the Leaf Spring Rebuild?

not enough pictures to make an informed decision. You did not include pics of the rear shackles. Sometimes people have the rear shackles positioned incorrectly. Also the shackle bushings and front spring eye bushing shouldn't be tightened until the car is sitting on level ground on all four tires, with all equipment installed. Commenter is correct, car needs to be finished to tell you exactly what you're dealing with.
