With the right weigh oil, you think they will seal with no problems?

I think where you're getting confused is the top of the piston- above the top ring- is a smaller diameter than the ring lands. Because of this, the area above the top ring is exposed to combustion chamber pressure.

This isn't something that's even needed on 99% of the engines used on the street. Even a regular tension set of 1/16" rings don't gas porting. And 1/16" rings would be something worth looking at if you plan on twisting the engine to 7K rpm.
