Thanks!
I'll be filing this.
Uh, anti friction lube? Would you use this on a the Coated Skirt piston?
So, Basically your saying you don't get assembly lube anywhere near the rings and use 3 in 1 oil in the ring grooves and let the rings pretty much dry?
   Call me old and unschooled on this, but I always used plain old engine oil and pretty much lubed the crap out of the bores and pistons with it. I take it I was doing it wrong?
  
   I never had a rebuild fail on me over the years though! No smokers or other failures. So I must not have screwed up too bad...

That's correct, except the last part..

Carefully lube the ring lands so they don't
abraise on start up - keep all oils off the rings
faces.

Run just a daub of light oil centered on the piston skirts to ease initial dry start up skuffing.

The dry fresh cross hatched walls are not to be oiled either - unless you're storing the engine long term.
 
If done correctly the dry rings will generate crazy heat against the dry crosshatch & seat properly almost instantly.

Keep the engine in an effortless sweet spot above 2k rpm for 
two minutes - not revv'ems - just floating around 2,300.

The old air cooled VW & PORSCHE flat fours had a reputation
for smoking - back in the 1960s.  

VW / PORSCHE AG drew info from the racing community & instituted the above procedures at the Factory and for Service.

No more smoking D'ubs - problem solved.

A guesstimate would be that back when, American engine piston weights & ring design / materials worked in favor of achieving
a ring sealing - even after a 'wet storage' rebuild .
