you need a steady flow of oil to the cam that can only be obtained by running the engine at 2000-2500 rpm gpt 25-30 minutes, or you will wipe out the cam. read the break in procedures of any cam manufacturer online. They give a step by step procedure
Maybe with hi-hp dual valve spring whumpa-whumpa motors... but stock/mildly warmed up.. no. Wiping a cam is just not a risk that most people need to worry about.. unless something is assembled wrong.
