New carbs??..

After 318willruns generous offer and another members mind blowing offer my day yesterday continued to be blessed!!..
Leaving me with a small budget for new carbs... Also a good little amount of work in the near future... Soooo my eyes are really looking towards the street demon..
$288 each is the best I can find and after a couple of days of work I should be able to afford that, but as always I would like to find someone to sell them cheaper LOL.. of course speed master has some carbs but these Street demons look so awesome and as I researched them I do like the way they operate.. Edelbrock Holly and Demon Parts on a thermoquad theory... I do like the idea of the composite Center and the cooling effects, but I find no overheating of my carburetors sitting on top of a tunnel ram... For the looks of the shiny ones.. in my research I hear people talking about the composite warping but that maybe the old composite compared to what kind they have now?.. again I don't even know if it's needed in my application...
