I would suggest at least 1 jet over what the carb came with when removing the intermediates, you don't want to be too lean at WOT. The idea is to get the low and midranges on the lean side, and the fuel curve in the range you run it WOT in as flat as possible. Pulling the intermediate bleeds may make it manageable enough an should show improvement, an as long as the metering blocks have had the mainwells opened enough you should have no issues getting it rich enough and the fuel curve flat without the intermediate circuit.
