Air Shocks

Yeah i thought about SS springs and shocks but was told it would lift it up alot but i plan on doing mini tubs and relocation the springs and if i do SS springs and shocks i would do that then. If i got the longer shocks for it would that lift it up? And yes its a original 318 car im pretty sure its all original except the motor its a 71 318 but the car was built February 12th 1972 but never looked into that mainly because i dont know where to look lol.
