"Cleanliness is next to godliness"

When I get a block or head back from the machine shop I use a gun brush and power washer to clean the **** out of it, every water and oil port, going from as many directions as possible to purge any shavings or crud left inside after machining. Then blow out with air. Squirt a little wd40 in the oil ports, antifreeze in the water ports, blow out with air. Wipe cylinders and surfaces clean. Dunk the pistons. Wear gloves since the natural oil on your hands is corrosive.
