After digging deeper into aluminum/steel galvanic action, it became obvious that during my initial research I was asking the wrong question. When steel and aluminum are together, aluminum is the anode and steel the cathode. If there is galvanic action between the two, the aluminum will corrode. The proper grease will prevent the galvanic action.
Couple of articles for anyone interested

I will mention that I am heavily influenced from the precision bolt rifle arena and much of my thoughts on marksmanship, trigger manipulation, etc, even rifle building pretty much translate to other platforms. In this case of the building process I can take a similar cue from the precision bolt rifle build where we blue print the action and true up the receiver face to the center axis of the bore of the bolt raceway. I know we are not looking for an alignment of gas tubes and barrel nut torque values as in an AR/M4, but might we get an added benefit of precision with the AR/M4 just like with the precision bolt rifle while solving the torque spec, or even tuning that torque spec to a desired value. Of course we might be talking different precision capabilities inherent to the rifles, but gas guns have come a long way.
Of course the simple thing is the torque and re-torque to get some extra give, but that will only go so far. I don't like being too close to 30 and some nuts will get you way over 80 if indexed to correctly when the low number is hovering around 30. Then you can try another nut. Easy enough if you have one, but in the case of some proprietary barrel nuts, you may not have more than 1. Another simple, easy to install and cost effective way to do it for those who don't have the need very often is to use shims. Heck some proprietary designs might even specify the potential need to use a shim kit for correct torque / alignment for rail attachment.
Last lapping. Not as cost effective for one or two rifles. While easy enough, not as simple as slipping on some shims, so what is the downside to lapping? Maybe removing too much material? Galvanic corrosion? Ahhh here we have arrived at that evil specter Mr. Galvanic Corrosion. Some people read too much on the internet or they really don't even understand what it takes to get a galvanic situation to arise or more correct, how simple it is to prevent it. It is surprising that some of these people go out in a rainstorm for fear of being struck by lightning. As mentioned in other posts, I too use grease during assembly and the correct grease as mentioned completely resolves any galvanic worries. The threads have ano on them but guess what happens when you torque on that steel nut? Yep, metal to metal contact, no ano, no sacrificial layer, no barrier. So we should be using grease anyway and lapping creates no more of an issue for corrosion if dealt with just like the threads.
Surf, you know more about precision rigs than i do. But I've been around enough precision builds done by buddies to know that truing a barrel to the action is a very early step in a true accuracy build.

Aeroshell seems to be the latest wondergrease. I still use Brownells ALP, which is moly-based as called for in the 23&P.
