Rev limit is as much a function of your valve spring pressure as the strength of your rods. I certainly wouldn't go above 7k to be extra safe as I'd start worrying about valve float depending on the condition of the springs. That said, I us a higher rated spring from EBS, with stock rods and J&E pistons and rev to 7300. Engine has withstood numerous accidental excursions to 8k.

That said, the last sustained one (oops I calibrated my tach wrong!) to 8k resulted in a spun rod bearing. However the damage was limited to the rod bearing and rod itself
