Heat cycle the cam and springs 2 times. Once to fill the car with coolant and the second wait tell it is warmed up and take it out for a nice cruse get 10 miles on it of so and then drop the hammer.

I've been told to keep it below 3,000 rpms for a few hundread miles, and to make sure to warm up the engine each cold startup......but I may be thinking of breaking in the valve springs........

My break in method was: let it idle, tune a little, drive it around for about 20min while scanning. Go back tune a little bit more ~20 minutes, then go out and see what it will do.

They don't need to broken in. I started my car up right after the install, let it idle for about ten, then stuck it on the dyno and took it to 7,000. 15,000 miles later and my car is running better than ever.
