Burr finish on carb spacer?

4 hole Q jet to square bore adapter/spacer. yes or no? Probably won't make a difference either way.

Are you shaping it or just putting a finish in it for some arbitrary reason?

Shaping

Well if you want to spend an extra ten minutes and breathing in dust, sand it. If not burr it and send it.

I would just burr it to shape and send it. Any gains you have will probably be from added plenum volume, and not the finish.
