Cold intake-air, or cold-air intake; is different than a cold intake manifold. You can have either without the other.
My 4-season DD slantys always liked the hot spot. And carburetor icing is a whole 'nother issue, and relatively easy to banish, even without the hotspot..
But you gotta think; at WOT, how much heat can actually get transferred to the intake air, especially if the carb is getting fresh cold air, which for most of us is kindof a mandatory thing to engineer. So IMO, for a streeter in most of Canada the heated intake is kindof a good thing to have. But in Macon........IDK,............. but I do know that down there,I'd try to run without it, given your stated useage.

My Eddie headed/AG 367 (no heat cross-over) loves it's cold intake-air. I only run it from April/May to early October.
When It's cold out, I just crank more timing into it with my dash-mounted dial-back timing gizmo, and babysit her for a minute or two (no choke, 750DP). But I can always feel the top end warming up after I hit the hiway; after about 3 to 5 miles the car begins gain mph without throttle input. Then I know it's time to start cranking the timing out. I always thought one day I would make that happen automatically, but for the week or two, at either end of the season, it hasn't been annoying enough for me.....yet.

I gotta tell you that gizmo is worth it's weight in gold, and once you start getting the hang of it, you'll wonder how come you waited so long to get one. Not only will it help you to determine your power-timing in less than 10 minutes, but it will also help you in choosing a cruize timing, your part-throttle timings and your Vacuum advance. With some combos you cannot set your D up with enough steady-state cruze advance, no matter how hard you try, and so she sucks gas big-time on the hiway. Here this device can really help you, especially with a 2-stage timing curve. And for bad-gas, old-gas or wrong-gas. And for cold start, or cold idle, and for Hot-idle. And for changes in altitude. I mean this little gizmo is a miracle-cure for everything.Well everything timing related.
