Stand back 
But on a serious note, you can prime the oil system by removing the fuel pump fuse before you turn the ignition on for the first time and cranking it over several times. Also I doubt you would do this but don't be in a hurry to rev the crap out of the engine. Use common sense and you should be fine. Everyone has a different idea of a 'break in' so im not even going to get started on that topic. Some say putting a load on the engine helps to seat the rings better while others believe in babying the engine until a given numerical distance. Personally I've raced my entire life on various motorsport forms and we beat the piss out of every engine right out of the box and there isn't any signs of lack of longevity or lower performance. I'm sure a skyline GTR turbocharged from the factory was put through its paces before it was delivered to the dealership to ensure proper functioning, does this mean we should do differently?
Here is some reading material on the controversy of break in:

One more thing is leave the rad cap off and let the car idle and top up as necessary. If at all possible get the car so that the rad is the highest point to 'burp' the coolant system. Keep an eye on your temp gauge and after the fans come on/off several times keep topping the coolant up. Cap the rad when the fans are on and the coolant is up. When the fans turn off the fluid in the rad will naturally rise due to heat expansion.

I will be starting my freshly built motor(sleeved, low comp pistons, etc) within the next couple days. Just wanted to see if you guys had any tips for me...
However, I am a fan of a "hard" break-in.
I bring them up to temp, checking for leaks like fluid/vacuum, then shut it down.
Tow directly to the tuner and break it in on the dyno. I break my motors in on boost
I'd also like to add, that using Brad Penn's break-in oil helps as well, has a higher zinc content which aids in initial break in and wear.
