Done it once, don't want to do it again, kind of a dirty & challenging job but if you want to do it yourself, I'd start with the steam cleaning you've already looked into, and then follow up with hand-cleaning with solvent and soft brushes. For the oil passages you can use solvent plus bore brushes aided with some compressed air. Lots of different solvents you could use, brake cleaner is effective and not too obnoxious.

If you're looking for a hands-off approach, take it to one of the shops that specializes in rebuilding these Packard engines like Automotive Restorations - perhaps 40 miles from Reading in Lebanon, NJ. They also have the equipment to line-bore your main bearings, or anything else all the way to a complete rebuild.
