Offy dual 1bbl

I don't even have a choke on my 465 holley and had no trouble starting it this week. We haven't had temp above 25*f in over a week. The lack of fast idle makes it so I have to sit there and hold it at 2000rpm for 2 minutes until it is warm enough to drive. The only carb heat I use is the heated air the aircleaner pulls from around the headers.
I missed out on a twin one barrel offie intake and linkage by about 3 hours at my local speed shop. He had the thing on the wall for years and then finally had two people ask about slant hop up part on the same day.
Those headers on the ebay link look like truck headers.
