Manifold Heater for Cold Climates

I must live in a different universe. I have Vixen's manifold heat totally blocked off and driveability is great even in cold weather. I drive her year round even in sub 20 degree weather. Even though I live in middle Georgia, it does get cold here. Even in cold weather, she's up and idling in under a minute. That's also with the choke adjusted WIDE OPEN and not even wired up electrically. It's never been a problem. I find it funny that when people add the Dutra Duals or headers no one talks much about manifold heat. I find it's a complete and total non issue.
