Welcome to the Corvette Forum Bobmaxk!
I just wanted to welcome you to this forum! Soon you will likely get answers from our resident Carburetor experts. I would imagine with some very careful and precise sanding/grinding you might make the surfaces able to flow air like they used to. I have some highly modified race carburetors and the grinding work is intense.
Good Luck with your project and I hope that you get the proper help in restoring the parts on your carburetor.
Best regards,
Chris

The roughness and surface finish indicates that you may have a commercially rebuilt carb, in which case you have problems much more severe than surface texture in the venturi. If it's a commercial carb, drop me an e-mail request for my "Commercially Rebuilt Q-Jet Problems" paper for an outline of the dozens of issues that will be affecting your carb. Your photo seems to show that you have a 1969 carb - many of those are commercially-built hack-jobs.
