That has nothing to do with VTEC or RPM.

I revved my stock GSR block to 9900rpms for oh i dont know, about a year. then i sold it, then someone else drove it for about a year before the oil pump failed.

If your motor rod knocked it was because of an oil pressure failure or an incorrect bearing size
