IMO, the use of performance improving upgrades is a balancing act. I have used all of the things you have mentioned but not without improving the middle main bearing's chances of surviving it all. I took pity on the bearing and used a counterbalanced crank shaft and pressure fed it. The others, I left with standard oiling. That motor has now done about 40,000 miles - most of them towing my camper which weighs about one US ton at 50 mph. Going faster is not the only reason engines are upgraded. I think I would have been walking a long time ago if I hadn't taken those measures.
