After much sweating and maybe a little swearing here is the weekend scoreboard.
Headstuds: 23 of 24 removed without lifting out the magnesium threads.
There is always that one that refuses to go along with rest.
P&C's
Yup, the 1,2,3 bank pistons also kissed the heads. I guess that makes a perfect score of all 6. At least we have consistency.
Crankshaft:
Visually looks good. only the lightest of scoring that can't be felt with a fingernail. Standard bearings in place.

With respect to the previously mentioned casting gate, the shrink is over the main webs, in a very thick section, and is indeed casting shrinkage. No chance of perforation of the case.
Initial visual upon 1st splitting the case was great.
But, then I got to bearing #7. Not good. Something went very bad. Either casting porosity, corrosion, or major fretting. I don't see any fretting on the other bearing web's. Likewise this is the only place inside the case that looks like this. I'm going to rule out corrosion as I can't see how it would be localized to just one web. That leaves casting porosity as the likely suspect.

Sent pictures to Ollie's today and they think all can be made well in exchange for $$. Likely to be on the order of $2600 to include potential welding, machining, line bore, adding case savers, oil bypass modification, extraction and repair of a couple transmission studs, etc. Life if good if you're Ollie!
10-12 week lead time to even get to it. Good thing I have at least a year!
Overall not a bad weekend! Beats being at work but I had to go back today to pay for this endeavor.
