You should be able spin it up to 11,500 or 12 K a few dozen times without hurting it.. mine hung together with stock rods, wild cam, 836 kit etc...
But, when I build my bigger meaner one I may consider using a rev limiter.
At first when you build a motor, all you thinks of is the dollar signs,, but if you get 10 years or a few decades out of it you realize its all FREE time.
I am not sating you cant kill them, but you can throw a lot of repeated abuse at it for a long time and they still live!...
What valve springs are you running?, I think if you have stockers it will limit it somewhat anyway..
