What will your break in procedure be? I am breaking in a rebuilt TR powered +4. 500 miles below 50 MPH, re tighten head and then go to beat hell and loosen it up fast. Not sure this is a good idea on a New Morgan. Maybe not a good idea on a rebuilt old engine. But, so far, I get a pretty good engine but not a pretty long life engine. I will change oil every 500 miles to about 2,000 miles. Oil with ZDDP added.
