Lol, just use some common sense.
Drilling the hole in the stat is an absolute benefit, I do all of mine that way. Raising the front of the car while you fill the cooling system will help "burp" it. Use a mix of water/coolant
When you prepare to do the breakin, make sure the timing is set right, make sure you have a good known carb. Make sure you have enough fuel in the tank to complete the breakin process. Double check your oil level.
It's real handy to have someone with you, one to operate the throttle, and the other looking for leaks and listening for problems. Mufflers at a minimum on the headers if you don't have the exhaust on yet. Much easier to hear any problem.
Have on hand, a fire extinguisher/garden hose if you're in a climate that allows it this time of year, a box fan for in front of the radiator, a screwdriver in case you need to tweak the carb slightly.
Fire that puppy up and have at it.
Good luck!
