Quick fuel air bleeds

Been emailing holleys tech support about my quick fuel carb. It's a Slayer 600 vac secondary. Mild cam, 360 28th 2.02 valves headers, RPM intake etc. Ever since new, my idle mixture screws have made the most vacuum and idled best when turned half turn out.still smells rich. If I back them out more vacuum and idle drop. Talked to holley, they said definitely go up a couple sizes on the idle air bleeds which I kinda figured anyway. This carb has a 2 corner idle adjustment, but they insist I have to change the secondary idle bleeds as well. What do you carb experts think? Summit is out of stock on the secondary bleeds but I went up to a 72 instead of a 70 on the primary side. Will just changing the primaries be enough or do I need to find bigger idle bleed for secondaries too?
