I always reckoned 'just drive it' like it wasn't any differnt to any other car. But have cool downs for the first 200km. So drive it and don't spare it [but don't flog it] for 10 minutes, then cool down. Then do the same again for 30 minutes, and then 60 minutes. Plenty of cool downs and even a check of everything to make sure you got it right.
Use run in oil and hills all OK. After this you could get it dyno tuned, but I'd also listen to my machinist/engine builder.
I'd also dump my run in oil at 100 and 500. 100 gets all the 'dirt' out, the little impurities and bits of metal that a new engine is bound to have. After 500 you don't need run in oil any more.
And run in oil is better for cast engines, not so necessary for moly or nikasil etc
