Yep, I ran them in 2 ops on the lathe. First I did the front radii and ID which has a 3.5* taper from the opening radius down to the throttle body, the second op faced off the back and did the external shape as well as the counterbore that fits over the throttle body. That is the nice thing about cnc, with a good program and set up you can make parts that are extremely close to being the same.
