1. 500 miles with a lot of in and out of wide open throttle to 3500 rpms, but only after engine is fully warmed up.
2. Oil change
After that, it's a matter of what you want to do.
It certainly doesn't hurt to keep up the initial break-in procedure but raise the limit to 4500 or 5000 (staying below vtec) for another 500 to 1000 miles.
Change oil again and go vetc.
The main thing is you want to force the rings into the cylinder walls by getting on the throttle a lot. Rings don't bite the walls from their own spring pressure, they flair out from cyclinder pressures getting behind them, via ring gap, gasports. Too easy on the throttle and you don't get the pressures you need to expand the rings.
That said, plenty of engines have been run to the max right after rebuild, but unless you have to race or have to tune, or there is some other reason, why hurry?
Virgin engines like a little foreplay.
