If you raise the rack but use standard tie rod ends, the angle of the steering rods will be pretty severe. You need to use a bump steer kit that moves the rod end to the top of the steering arm.
If you don't use a bump steer kit you can use the rack bushing to lower the rack in the frame; which improves the angle while using the stock tie rod ends.
