if it will adjust up enough, and doesn't interfere with any linkage, i would use that.
however, make sure the transfer slot is not exposed. if it is, you will have to make mods to the internals so the transfer slot is not exposed, and the carb will still idle.
the only other option may be to drill a small hole in the primary butterfly's, but that would be a last resort.
i can't say what mods will be needed, as i know virtually nothing about holley carbs, just carterbrock types.
others with much greater knowledge about holley carbs will certainly tell you what to do to solve your problem.
