like the others have said above, the oils today don't have the additives they used to. Add a quart of GM Engine Oil Supplement (EOS).
A lot of high end engine builders use Brad Penn oil for break in, like the NASCAR guys.

That being said, i've never had a problem breaking in a cam with the EOS, pre-lubing and making sure your engine fires the first time.
