Cam Install break in procedures?

[Cory_Langford at bcit.ca (Cory Langford)]

Thanks, I have a TT cam (new) to put in with new lifters.  I have heard 
from some people around here that there is a break in period.  I have seen 
one web site saying you should put in new engine oil and keep the engine 
rev'd at exactly 2000 rpm for 2 hours while the cam breaks in.

I guess I can just install it and go drive then, much easier :)
