Intrinsic vowel length

[Dennis R. Preston]

Anybody out there got a reference to intrinsic vowel length (not
phonemic length and not environmentally conditioned length). I'm
especially interested in [i] and [u]. I seemed to have in the back of
my head that one was intrinsically longer than the other, but the
usual sources do not help me.
