Detonation is not usually an issue when breaking in a cam. No load on the engine.
Get it started as quickly as possible, no long crank times. That's usually a lack of fuel and not enough timing deal.
Up to rpm 2000rpm
Put timing light on it and get 36-40* of timing in it.
Adjust RPM up and down a little 2000-2500 works pretty good.
Have all the tools you need to do this set up BEFORE ever firing the engine
Then watch for Murphy Law to arrive! LOL Murphy's Law
