I've had excellent results with a number of engines using Brad Penn 30 wt. break-in oil. Engine has Speed Pro low tension moly rings. New or freshened up engine has the 30 wt. oil in it along with a K&N filter when I pick it up. Engine is run while setting timing, valves etc. Leave oil in for the first time at the track. I make at least one easier pass, then race it that day with the break-in oil in the engine. When home I change oil and filter. I use 10W30 Brad Penn oil since my engine is clearanced properly for 10W30, and WIX racing filters. I usually change oil and filter after about 20 passes. The oil still looks good when change it. It could probably be left in but I don't. Engine is sealed up so nice I don't need to add oil between race weekends.
