proform race carb / Idle trouble

Well I am back at it! I had it sorted out last year by putting smaller idle air bleeds in it. Then I went and put a slightly bigger cam in it and the problem is back. I will be putting a vacuum gauge on it this week to see if I need to change the PV. For the curious ones, I put a Comp cams version of the .509 lift (.543 with 1.6 rockers) 292 duration in it. She runs good at full throttle. She is just terribly lean while cruising (throttle about 1/8 down). I've got to bump the throttle to squirt more to richen it up while cruising.
