I fill both sides #1 and #3 to the top all at once.

Here's a pic I found in the gallery that might make it easier for those that have never seen it.
Actually, this is a new aluminum case that comes cast w/ a solid area behind #3 instead of welding it in, but you can see the webbed area to the right of the crank on Glenn's case is a solid mass on this one.

I don't think I would trust a case with a bad casting like that one because if there is one bad spot there probably are others in the galleys or some other critical part where you cant see it until the motor blows up.

Do you see in the picture where the back of #3 is machined and the casting left a void? If you see that there can be other places inside the case where you cant see them. Ask muffler Mike about how many cases he went through to find one that was repairable. Or just go to his web site mufflermike.com and read about it.
I found his site very informative and it helped me to get back up to speed after a 10 year layoff from my turbo bug.

Sand cast... easy to have voids.

I guess i'll speak on Glenns behalf  - hope you dont mind 
Yes he is running the thickwall 92's but the base it turned down to fit into the OG 90.5 size bore 
You can also do this with 94's (turned down bases) but the cylinder heads are still opened up for the 94's |

It has been mentioned to me by a couple of people that a case that is welded behind #3, unless done perfectly, should be line bored as it is really tough to do this without distorting the case.
I ask becasue my case is a brand new AS41, welded behind #3, f/flowed, clearenced, bored, big-studded, etc.. I bought it as a package deal (otherwise I would not had it align bored).
Before I go to the trouble to assemble this engine (which I have a lot of $$$ into), should I have the bore touched up on it? I don't mind having this done it it save me headaches later.
Opinions welcome....

The place that you call a defect is normal. That is where the sprue or heat riser was attached when they poured the casting to prevent shrinkage at that spot due th the excessive amount of aluminum there. The oxides and other impuritiew will float and settle in the highest and hottest part of the casting. This case was probably poured a little cold but no structural defect.
