For block rust...look up RUST911, and order enough to do the block, mix according to directions, and leave it alone for 24 hours.
Flush good with water, the results will amaze you. I just did my TR-6 block in exactly the same manner that you described.
It's the ONLY way to get the rust out of the water passages. I have used it for several years now and am very pleased with the results.

: My "quick engine rebuild" fell
: apart. The machinist had a hundred
: excuses and reasons. In the end, it
: took him 12 weeks to work through his
: backlog and machine my 1500 engine
: parts. All the parts I removed,
: cleaned and bagged weeks ago will
: finally see daylight again. However,
: it has been so long I KNOW I will have
: a few questions about what goes where.
:
: My first question is about the large
: threaded oil galley plugs... the ones
: that are horizontal and located under
: the end plates. I have one that is
: long, one that is short. Do any of you
: know which plug goes under the front
: plate and which goes under the back
: plate?
:
: My second concern I have is the water
: jacket. The block was washed but I am
: cleaning it again myself. When I went
: to install the new core plugs I found a
: layer of fluffy rust on the inside of
: the water jacket. I would really like
: to get some or all of that out before I
: start the major part of the rebuild.
:
: I am contemplating blocking off the
: openings where the water pump housing
: attaches and filling the water jacket
: with phosphoric acid like I would use
: on bodywork. After a few days I should
: be able to flush it out and remove a
: good portion of the deposits. Do you
: have any other/better suggestions for
: how to clean the water jacket?
