Billy thanks for sharing. I also have seen the #2 main bearing issue. I would just roll another bearing in #2 at the end of the season.I drill out/enlarge the bearing from the oil feed I’m not really sure how well it works but I still do it. I think your onto something with the roller cam bearings giving the mains more oil. I think it was LPI that drilled out the main saddle oil feed hole and the lifter galley’s to make both bigger to increase oil volume. That might be worth a phone call to Mark Luhn.
Also in a extreme case I think Mike and Eric went above and beyond to feed the #2 main extra oil on their fire breathing nitro motor. There is a thread on here about that somewhere about how they got the bottom end to live.
