Josh,
You blew a ring for that very reason..once you did the great valve job, you
increased the compression in the cylinder and the weakened rings could not
hold the increased compression..viola, broken rings...common, and your
advice is right on, (in my humble opinion). If you do a valve job, at least
replace the rings too.

I'd be leary of doing a full valve job on on older motor (especially one
with over 100k) without doing rings as well. I had a 5 angle valve job done
on my new heads when I put them on my stang... I ended up having to do
rings about a month later because of severe blowby and watching a chunk of
ring come out the oil drain hole while changing my oil. (i always filter
what comes out so that I can look for particulates) I ended up having some
slight scoring as well.
