I agree with Brent, there is no sense arguing. Either you consider there may be an alternative to the factory grooving or not. I am certainly not telling anyone else what to do. I am stating what I know to be true and worked for me.i can assure you I am not a key board warrior. At the age of 77 my experience goes back to 1961 when I went to work in a small engine shop at the age of 13 which required a work permit. Having a model A needing new main bearings in the mid 60s my dad made the molds and found a universal boring bar. I hand cranked that boring bar more than I would like to admit. Once word got out that we could Babbitt and line bore. The first job for someone else was 1965. That lead to a complete automotive machine shop in the 70s in an industrial park. Yes I have poured a few hundred pounds of Babbitt and lined bore 200-300 fords. But I worked on all brands and all years so my experience is very deep. I could go on ad nauseum but won't.
