727 Time to rebuild

Valve body is all together. Went together smooth I’m still torn on the grinding on the throttle valve. I went about half way on it. Seems like there’s conflicting info on the matter some say if you don’t grind enough it won’t shift good may hang up first gear. Others say you grind it to the recommended .281” and I may lose downshift ability. I reached out to Tom hand for some wisdom. 7248FFF5-7229-437F-A155-A39230747995.jpeg9D00DEB0-5455-45A5-9DFA-F7358F8A69F0.jpeg B9A2663C-906E-4E86-AEA0-86FBEB235DE7.jpeg
