I used the tunnel ram package sold in the summit magazine. It has two 450 holleys with manual secondaries on each carb. I have the same cam as you with ten to one compresion. I use 3:55 and 4:56 gears depending on if I am racing or not. Either way the set up worked real well with great street manners and good power. I often wonder if I should have chosen the bigger carbs instead. I made my own fuel line for it and the linkage you get is not so great but is functional.
