There are only two "machining" operations typically needed that I know of.

Installing bronze bushings in the baseplate for the primary throttle shaft, and on some units I might flatten the airhorn just a tad if it's warped more than the main body so it can re-conform to it when it's tightened down.

I've read all sorts of stuff over the years about how the Q-jet needs all sorts of help to work well. They don't need much beyond calibrating them for the application and high quality/high performance parts installed.

Don't buy a cheap Ebay, Pep Boys or Rock Auto rebuild kit with a POS accl pump and tiny N/S assembly in it then expect to keep up with the powerful engine you just built. I get butt loads of calls an emails every week from folks who did exactly that. Most of them are wondering why they have a bloody nose when they bounced it off the steering wheel at the top of first gear when the car nosed-over on their first full throttle run!.........duh?.....
