Pre Lubing Engine Prior to Start

Hello folks,

After months of working outside on those rare warm days, I'm finally getting my truck back on the road after replacing the cam, lifters, and oil pump gears. I used assembly lube on everything, of course, but I would like to get the oil pump primed and oil up to the top end before I attempt to start it. With that oil pump driven directly by the crank, the only way I can think of to do this is to leave the plugs out, disconnect the inertia switch to prevent the fuel pump from running, and crank the engine over until I see oil pressure.

Is this advisable? Or should I just start it up and hope for the best?

On an unrelated note, I'm a little sensitive toward protecting my new cam and lifters, so I want to make sure the oil I use is good to flat tappet engines. I'm going to use Rotella T 15W-40 because it has 1200 PPM of ZDDP in the formulation. Should I be using a break-in oil for the first 1000 miles instead? Anyone want to recommend one?

Thanks, all.
