Bill,
weve probably been through this before, but are you sure that your
motor is really tuned proper?
Is the timing in specs?
Are you running lean at idle or cruising speeds?
The shroud may help a little, but be ceratain there is no underlying
condition that makes the car run hot.
The header tank is fed from the same water that is measured by the
sender, so the temp should be pretty close to the same in the header
as the sender.
Unless you are at about 5000 feet, pure water should not boil
at 190 deg F, and if you have any anti-freeze in there, the boiling
point should be 20+ degrees higher yet.
Sounds like you have a minor error in your temp sender/gauge.
You might also notice that the battery voltage has a significant
effect on the temp reading too due to lack of gauge voltage regulation.
Few alpines can run 30 minutes at idle without overheating, but you
should expect that the motor shouldnt overheat at a 5 minute traffic
stop.
