At what RPM will a stock D15B bottom end lose a piston or spin a bearing?

My friend and I are trying to build a D15 with an insane rev-limit. Yet, neither of us can seem to find any kind of information on this. We've tried several forums with only so-so results. We would be replacing the stock head with a completly built ZC head fully capable of 10K rpms. The only thing we cannot seem to find is charts, numbers, and experience with a setup like this. We plan on reinforcing the crank with ARP rod bolts, but would like to avoid dissasembling the bottom end for now.

Any help, suggestions, or tips would be very helpful. Thanks!

 

slightest ideas? anyone?

 

replace the rod and head bolts with arp. build the head and put high rev springs and retianers
