I personally do not think that either one of those solutions is needed on a big block with a stock cam. Just pour some eos on the shaft before bolting on the manifold, and pre oil before starting for the first time, and you should be OK. I have done a few, and Ive never had a failure. If you run a cam with steeper ramps and heavier springs, maybe then you will see a problem. From setting the valves on a BB while it was running, I can say from experience that they seem to pump plenty of oil to the top end, so I don't think that is the problem. You need
or you will get lots in the eye. If you are running a modified engine, maybe you want a roller cam anyway. With a roller cam set up, you will probably want to actually restrict some of the oil flow to the top end.
