QFT Jetting?

Hey guys! Hope everything's going well for the holidays! I'd appreciate some tips on rejetting my 580 Quick Fuel carb. Carb is how it came out of the box, drove all last summer on it. I thought the truck ran good, but it is a new combo and I feel it could be made better. I pulled the heads a few days ago and am in the process of doing a little bowl and port work. They'll then have a valve job and then be milled 0.02. Truck's got an RVish cam, headers, stock 727 but will be treated with a new stall and TF2 shift kit while it's out. The plugs are black. Very BLACK. So are the tailpipes. Anyone got any pointers? Anyone know what jets are stock in the 580 hotrod series? I don't see the need in dishing out the money for a full jet set if I should only step it back a size or two.
