The closest thing I can think of was from powerblock tv. On theri show "Trucks" they had a 49 Chevy truck with a 235 transplanted in it. They rebuilt the 235 on the sister show "Horsepower". I tried searching the past episodes for the video but did not find it right off. They did a pretty common sense rebuild showing a few tips and clearance checks. It may help you out if you can find it.
