I think if you lined up a bunch of mechanics, you'd find that many opinions on pre-lubing an engine on startup.
Most cam manufacturers have standards for using certain grease for cam break-in. A new cam is especially vulnerable. When I built a couple of different engines, into which I was going to install new performance cams, I actually broke in the engine with the old cam, then tore it down and installed the new cam.
This is because cam break in recommendations (at least back then) were contrary to engine break-in. The cam guys want you to keep the engine above a certain RPM (I've forgotten, seems to me that my old Sig wanted "not below" 2000RPM.) This of course is not exactly the recommended procedure for the REST of a new engine.
Now, as to cranking---that's probably better than running the engine, but you are still turning it over. It is VERY important to liberally lube everything.
I used to lube "all I could" and then use the oil pump shaft to make sure I actually had oil flow. You have to bump some engines over to get oil to the rockers, because the cam must rotate to line up the oil transfer holes.
I'm a big believer in a drill driven primer. You can make SURE that the pump/ filter is delivering oil, and that the oil is getting clear up to the top end.
THEN you can concentrate on watching for other problems, like leaks, etc, get the timing and idle set, and so on. You can keep a wary eye on the pressure guage, but you don't need to worry, then, about the top end/ rockers.
