Wash the entire block with warm water and dish soap. Rinse it real good with cold water. Dry it with compressed air. Spray it down with brake cleaner. When that dry's I spray a light coat of WD-40 on every surface. Check all your clearances, check them again. I then install the crank dry on the bearings. DO NOT, I REPEAT, DO NOT turn the crank when it is sitting on dry bearings. I then check the numbers I got with the micrometer with plasti-guage. Another words I check again. When I am happy, I will start assembling the short block for real. Take your time and check everything at least 3 times. It takes all day, but it is worth it in the end. Good Luck and Enjoy.
