I have coated manifolds, an engine that I have temperature issues with, 
and the last thing I tried last August (I live in Arlington, Texas), was 
to remove the shrouds. It started taking 10-15 minutes to warm the 
engine up to decent operating temperatures. That can not be a good thing 
for any engine. I parked my car last summer rather than operate it that 
way. I had Corvairs in Houston Texas for years during the 70's and early 
eighties. One thing that was never a real issue was overheating. We ran 
them hard, but as long as everything was functioning correctly, rarely 
had issues with high temperatures.  We had a 65 sedan, 110 hp/pg/AC. We 
called that the "link trainer", because my entire family learned to 
drive in that car (it's also ironic that I have worked for Link Flight 
Simulation for the past 20+ years). Then a multitude of 140 hp coupes, 
which were simply flogged around town. Only time we ever had problems 
was when a belt would separate. We drove those cars all year round. 
Maybe that's wishful thinking balanced by a couple of decades of 
waterpumper usage, but that's how I remember it.

I am very interested in this thread, because it would seem that Bob has 
hit the nail on the head, where all I have been doing is hitting my 
thumb. I will be interested in the results when he switches out his 
manifolds.
