If your port closeure is not exactly phased, your per-cylinder timing goes off the wall, which is a bad thing.
If your quantity is off, you get mismatched power, excess vibration, and etc. Also a bad thing.
Changing a plunger/barrel assembly nukes both of those adjustments.
Best bet is to get the Bosch MW 6 cylinder service manual that's floating around, read it, and get a feel for it all.
There's also some service training slideshows floating around on the governor, and what it all does. With luck, we'll have a less grey-area resource on the governor soon.
