Too late for you now, but for 25 years I've dumped the oil and changed the filter always right after the first run (Cam break-in). Then again after the first day of test driving and tuning, which may mean a couple of hours total run time, or 20-40 miles. Then AGAIN at 500 miles, and AGAIN at 1000-1500, and then fall on your regular schedule. Filter every time too up until that point.
The first run is with regular mineral oil, nothing special, no extra additives, and especially no friction modifying stuff. Good ZDDP oil is ok. All the other commercial additives in a can are a no-no.
