Sounds good. I assume you mean .009" ring gap variation, not bore size, right? Do a good glaze-breaking procedure with a flex hone or something similar, followed by a thorough scrubbing with HOT water and detergent like Tide or dishwashing liquid and a stiff-bristle brush, followed by several rinses. When the cylinder walls flash-rust as soon as the hot water evaporates, they're clean enough. Do a wipedown with motor oil to prevent further rusting until the engine can be assembled.
