Yeah, you need to crank the motor over a bit to circulate some oil in there before you actually fire it up. Unplug the coil pack, and there are fuses that will kill the ECU and fuel pump. Or, actually get at the fuel pump and unplug it to be safe.
I've only got wagons, so the fuel pump is easy to get at
I would also have all this ready to go RIGHT when you pour the oil in. I would pour the oil in just a minute before cranking, that way at least the drivers side head might have a bit more oil than usual.
I figure it may take a full 5 quarts to fill up at first? anyways, it will certainly take a good bit more than a usual oil/filter change. after some cranking with no spark or fuel going in there, fire it up and break it in. full cold to operating temp. I like to break in 4-choke motors like this guy,

my 2-smokes, are another story, little different on break-in.
