well leo capaldi, as far as i can tell has run his (on the dyno at least) up to 8500 with stock rods, and runs it to 7500 on a regular basis on stock rods. all he's changed is valves, valve seats, bearings and cams...
so if the stock valvetrain can handle that many revs, and the rods can, all i'd theoretically REALLY need would be rod bearings and cams to make the power up there?
