Steering Q after having head gasket replaced

I just had the head gasket replaced on my 03 Montana and as I drive away from the dealership I felt that the steering was stiff. I have been driving it around for the past couple hours but it doesnt feel like it used to pre-head gasket repair. I havent called the dealer yet. Can anyone give me a heads up before I take it back? Thanks!

check and see if there is power steering fluid in the power steering .as the line had to be loosened and they most likely didn't fill it..

The easy way to change the heads is to drop the engine and do the work in the shop out of the car. This requires the steering shaft be disconnected and later reconnected. Most dealerships would drop this engine to change heads.
After you check your fluid, ask the dealer to inspect the steering linkage if they had it apart. It may not be seated all the way.
