Rack and pinion steering.

20.1 manual box will be my best option
That would be a good choice. The OEM stuff works to a great extent and it gets to a point where something(s) dictates spending a bunch on non-OEM stuff.

Look into the electronic power steering swap threads. Added to a 20:1 manual you get rid of a belt just like r&p to reduce parasitic loss. Crisp steering with the ratio and power with electric. If your headers fit with a manual box then go for it.
