Let me offer a word of caution about shooting in confined spaces, and yes, an 8 foot ceiling is a confined space.
The strobes will kick a lot of light out and that light will bounce around a lot. Most studios have high ceilings and somewhat distant white walls to minimize light from bouncing back.
It's not so much that the light bouncing back hurts the exposure, it's that it may pick up color casts from whatever it bounces off. Say you have a red ceiling, you can expect to see some pinkish cast to your images in a confined space.
So the question is really can you control the color situation. If the ceiling is pretty close to white, you may not have a problem other than watching for unwanted reflections. It can actually help by providing additional fill in light.
The same holds true for the walls and floors by the way.
