"You sure don't want to do that until you know the oil troughs are full."

Of course not Tiny , he's not even going to start the engine till he works up some oil pressure , Zacca asked "is there anything else" my added info was for after it was first started , in the interest of securing the cam run in.

If the engine was correctly assembled then the cam will have the appropriate cam lube on and it only lasts a short time before it is wiped off , hense the need to get oil flowing before startup , then keeping the engine running so splash lube is fired around inside the block to lube the cam/lifters adequately.

If the oil pump is working , and there is no reason for us to assume it is not , then the troughs will be full from a few seconds after the engine is running such is the volume of the oil pump. The pre priming is to fill the oil galleries and give a wet surface to the bearings for the initial rotations of the crank.

No arguement from me , more oil is good.
