Dean,
You may be right. I don't think it takes the thermostat very long to
open up and I have not had any problems so far. I have the thermostat bulb in
the head right by the thermostat and it seems to read the warm up pretty
fast.

Let me tell you why I think that is
bad.
When the engine is cold,
the thermostat is closed and because
the bypass is blocked no water can
circulate through the head AT
ALL.
So what could happen is localized
heating could occur in an
area of the head/block that is far away from the
thermostat.
Eventually the front of your head will get warm and open the
thermostat, but it may take a while.
Basicaly you need some flow to let the
thermostat "know"
things are warming up.
The benefit of running with the
bypass blocked is that none of
the hot head water gets mixed with the normal
flow, so you get better
cooling.
The downside is longer warmup time
and running too cool
in colder temps.
But since you have a blocked bypass
like I now have, then you
should not run with the thermostat (or open the
bypass)

My bypass is blocked and I have a thermostat. Never
runs
over 190 to 200 degrees in Southern California.
