Apparently, the 'good' flushes have been taken off the market; at least I
can't find them on local shelves any more.  But my local radiator shop has a
process where they blow a mixture of water and air through the engine, that
seems to work well.

The other thing you can try is removing the plug (or valve) on the side of
the block, and probing through the hole with a stiff wire.  Then flush water
out the hole until it runs clear.  Lather, rinse, repeat as necessary.
