Ride height and replacement leaf springs, '63 Dart

[Stunt]

I need to replace the leaf springs on my '63 Dart, and want stock ride height. Does anyone have any experience with the Mopar Competition Leaf Spring that seems to be available from multiple vendors? Wondering if they would lift the rear too much.
Here's a link to them on Mopar Performance Online: Mopar Performance Competition Leaf Spring - P4120863

Any help is appreciated!
