I'm sorry Scott, but your reply makes no sense to me.
The only things I can see that affect the clutches holding ability are the spring pressure from the pressure plate, the surface contact area between the flywheel - clutch disk - pressure plate and the engine RPM.
I don't see how resurfacing a flywheel would effect any of them.
Now if the flywheel is not supposed to be flat the surface area would change.
I've been looking at replacement flywheels. They all say that they are of the flat type.
