Leaf spring shackle angle

Got them from a restored 71 demon. The owner did a complete pro street 4 link set up a near by chassis shop so I picked up the springs with hangers and shock mounts u bolts tti exhaust system driveshaft torsion bars all pretty new. I installed on a 8 3/4 I picked up but didn’t loose the hangers from front eye and shackles just put in as was. And yes 6 leafs no half’s all looks equal lengths.
I’m thinking of loosening the ft eye pivot bolt and shackles bolts and re tight with weight of the car. I just got the rims and tires Friday and that’s when I noticed it was so high.
If they’re not ss springs why is it so high?
