Cam break in

Just finished the first part of my cam install last night. I'm running a TSP Tsunami Cam (ground off of a Comp stick), and PRC dual valve springs with hardened push rods.
In the comp instructions it says to remove the inner valve spring and run the motor at 20min @ 2000rpm. I was checking on Ls1tech and they say that the hydraulic lifter engines don't require breakin like the flat tappets of old.

Anyone done dual springs, and if so, what break in (if any) did you undertake?
