Does this stretch bolt issue apply to a 2.0 air cooled?

thanks

hi..
talking with an engine supplier I'm getting rebuilt 2.1 from ..
they say 2.1's do that due to the stretch rod bolts eventually stretching
more ..
that usually leads to increased oil clearance on the rods ..
which may lead to rod failure, thus ventilating the case.

they say 1.9's don't do that due to using a non-stretch type rod bolt..which
they assemble 2.1's with now.
and
with the longer stroke of the 2.1 there is the increased angle affect, as
pointed out by Dennis yesterday.

btw, this engine rebuilding company I'm talking to will even built a 2.1 in
a 1.9 case since some people think the 1.9 case is stronger ..
but they say the cases are identical in construction ..
and it's the 2.1 rod bolts that are the cause of blown 2.1's.
