DP Hemi - Hydraulic Roller Lifters

Are the DP Hemi's in Stock running 100% stock OEM lifters or are they being shimmed to within .015", to run the RPM's they do?

Ours are OEM stock and run up to 8400 rpm with no problem.

Thanx for the info!! I've heard that valve springs are more of the key to high rpm than the OEM lifters.
