Well, hard to say from here but if the proper Part Number Shocks were installed it should not have changed the ride height.
What some have reported is that when doing any front end work and all is not final tightened / torqued with full weight on the Car this situation happens.
Suggest if this is the case to Lift the Car, loosen all that was worked on and retorque with full weight.
This can be done in a Pit or placing the Car Tires at some height on wood blocks or similar. Just be careful !
