the only person you should see about running-in is your engine builder he will tell you what you should be doing,
i use millers running-in oil, yes they do a specialised oil for that very job... i will do 400 miles ish and cycle between 3K and 4K alot and also not be to gentle with it... try and get to allsorts of loads, up hills ..over run ect.. thats how i do it and never had an issue whatsoever.
good luck.
