The Cosworth motors that I have done some break-in on the dyno come with some rediculous steps to go through. Like 10 minutes straight at X RPM making X ft/lbs of torque, then 20 minutes at X RPM and X ft/lbs, then 10 mins at X RPMs making X ft/lbs, and more.
Getting the A/Fs dialed in right away, doing a bunch of vaccum pulls and changing the oil a bunch of times seem to the most important things.
