First, there are any number of techniques that have worked for different builders over the years. What I offer here is the techniques we've developed over 35+ years and well over 400 911 engine builds.
Now to the meat and potatoes.
Main bearings* are installed dry on the back with a coat of your favorite assembly lube on the face. We dry film (Moly) coat all of our bearings but that is an option for the builder to decide.
* Over the years we've found that a thin coat of 1211 on the #8 main saddle is good insurance but not necessary if the case/saddle is perfectly round....I've measure that saddle .015" out of round.
Applying 574 to the main webs is for the experienced builder only. You must apply a very thin coat and the case halves must be assembled quickly and with confidence.
Too much glue, too slowly assembled could result in oil pressure diversion.
We still use Curil T on all surfaces prone to movement. Cylinders move with expansion so Curil T on the base gasket is advised but not necessary.
