Hello Steven,

I have had excellent results using Hoppe's bore cleaner (available in
sporting goods dept., but not the 'gun oil') and a rough, clean rag. 
Use very sparingly.  Whatever method you use, don't remove any metal
from a machined surface.  And don't sweat the rust on the rough cast
sections of the block as it doesn't matter (unless its very deep).  The
heat of a running engine will take care of it.
