I've been fine so far (cross fingers), and I definitely beat my engine up mercilessly mid-corner. Just good cooling (rarely cross the 220 oil temp mark these days - sometimes 225, but I can't even remember the last time it hit 230) + the AMPerf baffled pan. I also keep my redline down: in UpRev I have my soft limit at 7450 and my fuel cut at 7600. It's not worth the reduced engine life to me to try to squeeze an extra few-hundred revs out of it.
I'd love to rebuild the engine with stronger internals, better bearings, and a dry sump. But for that kind of money, I'd rather drop in a cheap and well-prepped LS1 conversion, since there's no rules prohibiting me from going down that road. For now I'll keep trucking on what I've got until it blows up and triggers the LS1 process
