Header coatings, how necessary?

I remember Denver. Used to drive my car down the frozen streets, cut the wheel all the way to one side, pull the emergency brake and do 360s until the car came to a stop or I hit a curb!!!LOL
I also remember my lips and ears getting cracked from the low humidity. I thought it was cold in Denver until the military shipped me to Cheyenne, Wyo. Denver's a mile high, Cheyenne is 1000 ft higher. When I finally came back to South Texas I swore I would never live in that freezing cold again.
But one good thing...that's where I fell in love with Mopars, had a Roadrunner (383, 4spd), Belvedere, Dodge W350 4 X 4, 3/4 ton (or one ton) military truck, all original 1970 440 6 pack challenger w/shaker hood, '67 Barracuda 273, 4 spd...all while I was stationed there.

When I finally left for home (Texas) I had to leave behind 5 complete 440 engines that I had collected. I remember paying $100 a piece at the junk yard. Didn't have room or weight capacity in the U-Haul for them.
