Default Switching to Coil Over HELP

We are in the process of rebuilding a 1967 GTO and have come to the front suspension. Looking into coil overs from either AFCO or possibly Viking but am open to other brands. The car was 3500# with me before the rebuild. Since then a roll cage has been added as well as some more bracing on the frame and a mid plate. Switched from front drum to strange disc brakes and replaced factory seats with light race ones. Motor will be an iron headed 455 in the 650 HP range. Possibly more. Will the coil overs bolt right in or should I consider new control arms for the strength. I am also not sure on the spring rate. The front needs lowered at least 2 inches from where it was. Car is drag race only.
