I like to change the oil and filter after the first fast idle warm up to remove any residue from the rebuild. I like to change the oil and filter again after 200 miles just because.... oil is cheap and engines aren't. Some folks will not change either oil or filter until 500 miles - the choice is yours, but after spending the time and money to do a rebuild, the oil and filters seem like cheap insurance to me. You could certainly extend the second change to 500 miles if you wanted to, but I sure would recommend the first change immediately after the initial fast idle warmup.
