If you hear your lifters ticking badly, you've bent them depending how long you revved in that 9K range (1 sec, 3sec..etc.) and would assume it was a 1-2sec there. As for your car, your fine, as long as you stay in the 8.3K range. Just don't blow the engine the next time you power shift, you are driving a highly revved engine.
if it slightly went past 9000 for a short ass time ull be fine...ive misshifted my r18 up to 9500 rpm for 0.5 seconds max...got a compression test, oil change, no metal filings everythings good...just dont do it ever again
