Bill, IMO there's no need to "hot tank" the block. With the liners out, all
the water passages in the block are readily accessible. Plus, for whatever
reason, several people have had trouble with paint adhesion; and this is a
particularly unpleasant place to have that problem.
However, I agree it's a good idea to pull the liners out and clean out any
rust/scale that's present. I used a wire brush in a die grinder for most of
mine, and touched up the places the die grinder wouldn't reach with a "steel
toothbrush". You could even use Naval Jelly if you want, but IMO these
surfaces aren't all that critical.
