After I rebuilt the engine I broke the engine in by using conventional oil for the first 7,000 miles. I changed it at 500, 1,000, 2,500, and 5,000 miles. I noticed a lot of metal on the 500 mile change, but that decreased over the next few changes. I had a good deal of blow-by the first 2000 miles, but that went away too. I did this on regular gas using normal driving habits. I would also get a little more aggressive at times. The thought behind this was that the engine would run how I broke it in. I do not know if that is true, but it made sense to me. I switched to synthetic oil at 7,500 miles.
