You would be amazed how easy it is to wipe out a new cam/followers if you don't.......(Don't ask!)
The advice you've received is good but try not to lug the engine during the break in period.
It's not good practice anyway, regardless of the age/condition of the engine.
All that achieves is excessive engine wear and wastes gas.
The oil change is critical too as this first fill will effectively flush the engine and trap any 'nastys' including the initial break in wear.
I would change the filter too.
The extra $$$ spent now will pay dividends later.
Good luck and enjoy!
