 I never understood why #3 runs hotter than the others, maybe
 it's the fan
 design.
 

The oil cooler cuts the airflow to #3 cylinder.  Even though it has its 'doghouse' it still restricts flow.  Here in Phoenix those upright A/C motors don't live long in buses unless you use an external oil cooler.  Burned a couple myself in my '68 before learning that one.  And you really have to keep the RPM's up under load if you want to keep it from frying.

FWIW, I used the crush ring gaskets on my '78 2L when I built it for my Westy.  The long time VW mech/machinist I used always used them.  Ran fine for 95K until an injector hose blew and it burned to the ground.  Learned that lesson the hard way too.

Still haven't learned to give up on Westies though...
