Running without a thermostat ok?

I think most of us will get a little peeved one time or another when questioned about something you know worked for you. As I have found the reason you thought it worked may not be right at all or only partially correct. There are many different problems that display the same symptoms. This thread has been great in bringing out a lot of issues related to the cooling systems of our machines. I had forgotten about the lower hose spring issue. Slowing down the flow depending on where you restrict the system also can keep pressure in the heads where it is needed and prevent steam pockets. Too much total timing at cruise was a culprit in one of my slants. When I worked at a GM dealership there was a problem on several models that would overheat at cruise if the lower valance or air dam was missing or damaged. Missing shrouds, bad fan clutches, even too much antifreeze. Straight coolant does not conduct heat as well as water or the mixture. Eliminating the EGR without compensating mixture and timing is a sure way to heat one up. When a thread gets as long as this one it does get to be a pain to read all the way through and I'm sure I have asked a duplicate question a time or two because I sped through the post. I don't mind getting tagged as a dumb butt for being one... ;) I just hope guys don't give up posting some of your great knowledge and experiences. A good example of what not to do is just as valuable as technical expertise.
