My two bob has always been if you want to accurately control the bore diameter across a joint you gotta have metal-to-metal contact on the faces then use an effectively zero thickness sealant. Putting something in the joint that you want to squish to a final thickness is opening up a can of worms.
The final thickness has to depend of too many things - how slippery the flange faces are, the temp its assembled at, bolt tension, bolt length etc.
Also I'd expect the gasket to creep thinner over time, closing up the bore size, and this would be affected by how hot, how often the engine has been.
If I was my own bike I'd try the gasket, but I'm a rough bästard. If I was putting it together for someone else I wouldn't.
