I'd suggest clamping all the spring leaves in the front segment to the main leaf.
Wheel hop is caused by the front spring segment bending into an "S" shape. When this happens the spring overloads the shock and can not control the spring.
Also make sure the pinion snubber isn't touching the floor need at least 1.5" clearance if using one.
Quality shocks are always a good idea.

All that's on my car is leafs, QA-1 shocks and no snubber and she'll 60' high 1.38's - 1.40's footbraking.
