Slant six builders...Lets talk Cams

Hey guys sorry to barge in on this thread but I wanted some ideas, Rainy Day Auto I have bought the comp cams kit and the install was straight forward, that being said... I have the comp cams kit, offenhauser intake, holley 4160 390 cfm, and hooker long tube headers. I have gotten the car to hold an idle now after playing with the timing (I had to jump a tooth on the dizzy) the car will idle at 1000 but will climb up to 1300 and with the hood closed it dies and when a gust of wind blows by (the beautiful San Diego breeze) RPM's will climb. When the accelerator pedal is barely tapped RPM's will climb to 3000. Nothing major done to engine, head cleaned up all valve guides done. Seems like a vacuum issue to me but no leaks. Any ideas as to what may be happening?
