Caster corrects the steering , most of the front end will swing easily so maybe disconnect the pitman arm from the center link & see if the steering moves ok , possible the steering box is causing an issue
I would still use a cam Other than Comp or Melling , Voodoo series work extremely well in Mopar . Get a Double roller timing chain
If you use the stock 318 heads I would open the port to 340/360 size the smooth flow from the larger intake ports in the manifold into the smaller head ports

Never been a fan of KYB , if the springs are moved inboard I doubt you will need longer shocks as the shocks will be be more compressed with the lower mount inward .
QA1 Rancho & Bilstein are all great shocks , definately want adjustable to control the rise tho .
I just do them myself , turn the front upper control are eccentric all the way out & the rear all the way inward , using a digital level or your smart phone adjust the upper control arm until you have 1/2 * of neg camber & set the toe in 1/16 using a tape measure
