List,

I can only contribute my experience.  I had a 91 GL in which I put a
Boston Bob engine.  At the same time,I replaced the thermostat housing,
the plastic distribution piece on the right side of the engine, all
hoses, expansion tank, etc.  In other words, every piece of the cooling
system in the engine compartment.  I used OEM spring hose clamps. I then
filled up with Dexcool.  Over the next fee months, I saw evidence of
seeping / leaking in many spots.  Hoses seeped, thermostat housing
seeped, etc..  I then drained, flushed and refiled with regular green
antifreeze.  This ended the problems, leading me to conclude that the
orange stuff was the cause.
