I am in the same process. here is my method for a top-end rebuild with new cams, rockers and complete head work.

Break in the cams at 2100 rpm for 20 minutes. Wait another bit of time until the thermostat opens on the oil cooler. Shut down engine and drain oil.

Next day, go for a drive. I went to the store for gas and back. This is to just warm up the car. Upon return check the car for leaks. Make sure to monitor all gauges. I have an external EFI with more information and I find this helpful.

After the initial drive the car should be warm. Go and and drive it hard. I found an empty road with a decent speed limit 55. Put the car in 3rd and pull from 2500 to 5K with lots of load. Foot down until the revs come up then let the engine brake itself down. Downhill engine braking works great. High load up the hill, engine brake down the backside. Rinse, repeat. After about 30 minutes I increase the rev limit to 5500 and to 6K after another 30 minutes.

The next day, drive again the same way. I am a believer that engine braking down a hill is the best way to seat rings. Going up the hill creates high load to push down, and out on the rings. Down the hill creates high cylinder vacuum pushing up and out on the rings.

At some point you should notice the engine is starting to have more pressure to the engine braking. The feeling is that the engine has more ability to slow you down when you take your foot off the gas. When you feel this your rings are breaking in.

Mine took about 2.5 total hours of driving to get the feeling.

YMMV
