Yes. The angles increase. The simple way you correct it is with a dropped pitman arm.
When you do bigger lifts like SOA and soa with lifted sprigns, the way you fix it is crossover steering (so the tierod is above the springs instead of below, thus reducing your draglink angle). Basically, you want to fix it so the draglink angle remains as close to the stock angles as possible. If you don't, you get what's called bumpsteer. This is where when you hit a bump, your steering wheel turns. When it gets to the point where you get unwanted lane changes, it's time to fix it

FWIW, i have an SOA and a 4" dropped pitman arm, and my bumpsteer isn't bad at all. I attribute that to a wider front axle, which makes my draglink angle less than what it would be on a narrower axles with similar lift.
