Thanks! Yes, described previously in this thread. http://www.moyermarine.com/forums/showthread.php?t=8979
Have to be honest and say it was a completely irrational PTSD response to a bad cooling experience. The A4 can and will live with less, but I wanted to try and replicate something like the original side jacket casting. I'm not sure I'd do this again.

The home made electrolysis, can you explain more? Was this used for rust removal or paint removal? How did you remove paint from block? I was planning on aircraft paint remover...but if you have a better alternative, I'd love to know about it...
Removes rust and (loosens) paint - the bond fails and the paint falls off. Described previously in this thread. http://www.moyermarine.com/forums/showthread.php?t=8526 As I mention in the thread, this is not my original idea, but something common in the old tools / old iron community.

After I found my block had been recently rebuilt (that was a really good day), I took a calculated risk and didn't separate the main castings (rear housing, block, and oil pan). I cleaned them with solvents and wipes, and did some sanding/wire brushing to make the surfaces as friendly as possible for the primer. I used the POR spray acid etch to prevent surface rust and add 'tooth' on bare metal.

It really depends on how far you're planning on / need to disassemble. If I had fully disassembled, I would have taken the big parts to get hot tanked and started from bare metal. My tub was big enough for the flywheel housing and everything else.
