As the cam/followers need 20min's of good, clean, high pressure/flow of oil to reduce chance of wear.
It needs to be @ 2500 rpm for the oil flow/pressure
and for 20mins, as it needs to beheld with the oil flow/pressure to after oil got to working temp.
Also i think some of its to cover the cam producers back.

i usually do it @ 2500 rpm till oil temp has pasted normal running temps and all adnormal noises have dissappeared.
You see though..........CVH top ends are poor enough designed as it is, have you ever taken the cap off immediately after starting it from cold and seen how much oil there ISN'T flowing across the top end .....?!

Additional to the fact they have very excessive spring pressures, i would of thought raising the RPM that high would ruin it more than anything, especially when the oil is cold and thick............
