Mating Surface Prep

Corroded Dowel Bosses

Here's a unique problem with Ford block decks: dowel bosses. They corrode and have to be cleaned so new dowels will sit correctly in the bosses and line up the heads. In situations were the surface is tough but recessed in a way that a brush won't work, use a small flat blade screw driver (or similar implement for different surfaces) and carefully swirl it around, then wipe it out with cleaner on a rag, or bottle brush, or both.
