Any gains you would get from not running a base gasket would be minimal and unoticeable at best. The base gasket isn't very thick to begin with and either way you're going to want to run some type of sealer or gasket type material between your cylinder and the cases otherwise you could get contaminants in your engine or even leak oil. If you want to really "true up" your compression ratio look into either getting the head milled or the top of the cylinder cut down. I have the top of my cylinder cut down .006. I did this because my big bore sleve decided to sink into the cylinder between rebuilds.

I agree, the gasket is so thin to begin with it won't really matter. Plus as he said if you put some type of sealant on it you risk putting things in the motor you don't want.
