Cobalt is right on point with this. With all the plugs removed from the oil passages (including the one under the rear main cap) it's something you can do yourself. If you're going to brush hone the bores now is the time before you wash it. Using hotter water will slow down any rusting until you can get it dried off and WD40'd. Then once you've done all this install the cam bearings and oil plugs.
