Same. 
Wrapped my steel headers in 1995. 
No issues to date with them. 
Replaced mufflers twice, but that's a road abrasion issue due to my lack of ground clearance...
Best
Chris

Great for a day sail on the Harbor which I will do in the next hour.  However, it does make driving a hot car fun. There is not enough cooling capacity in the stock radiator to handle hot climates and have to stop and go because the temperature does not go down only up.  So the next step is to re-core the radiator.  The local radiator guy knows the problem and for $500 will provide new core using the old tanks which will give at least 50% more cooling capacity.  This is a SKI purchase.  Spend the Kids Inheritance.  Then I will think about wrapping the exhaust manifolds and headers to stop vapor lock.

>> With the extras that you have added to facilitate the airflow the car should be running much cooler than 212, even with a stock radiator. There is something else amiss in the equation.

As a pusher it really pushes air through the engine compartment at low speeds and standing still. I still have an original Texas 6 blade fan on the engine.  As I was searching overheating problems, one reference indicated that is not recommended as they act against each other.
