Someone, whom I can't now recall, posted the link below for the subject
article. I highly recommend it.:

​It's certain to generate some interesting controversy since it makes a
flat statement, with good rationale, for using ONLY manifold vacuum, NOT
ported, for timing advance. What it does not do is explain in detail the
changes in centrifugal advance that should be made to compensate for
changing the GMCMH from ported to manifold vacuum. But it does explain why
some changes may be necessary.​
