I don't think the washers have anything to do with a lean condition at wide-open throttle and high-revs. At that point needle will be almost all the way out whether there are washers lifting it or not. I'd think the question is, with the snorkel removed and a more free-flowing exhaust, can the carbs get enough fuel into the mixture to maintain the proper air/fuel ratio at max-rpm, max throttle?

I don't know the answer to that, but if the answer is that the carbs can't, then there may be actual needle changes necessary, and shimming won't fix the problem. If the answer is that they can, then once again the washers don't matter.
