FWIW, this is on my 3.2 with .5mm bare copper .5mm gaskets.

I only recommend 1211 in certain applications.
The best product we've found for cylinder bases with copper gaskets is Curil T. It never hardens so assembly time becomes a moot point.
As for the comment by our resident antagonist: We use Dow 55 on
all case o-rings (chamfer or not) with exceptional, long term results.
Edit: we actually use Dow 55 on every o-ring during the air-cooled 911 engine assembly not just case through bolts. It works exceptionally well on oil return tubes, cam joint rings, RSR rocker shaft seals, cooler seals as well as all rotating surfaces within seal.
