All over,

Had a quick question, I know there is a million engine break in posts but, I have been reading throughthem and have not found an answer to what I am looking for. I just rebuilt engine from block up, new bearings, rings, etc and I put non synthetic 10-30 in my car and let it idle at 2000k rpm for about 10 min, then I took it out and did a 5 5500rpm pulls and let engine bring itself down. I am wondering three things though. One, is it ok that I used 10-30? I read another post that said to used 10-40. Two, how many pulls should I do for the rings to set? Should I just pay close attention to vacuum gauge until it starts reading normal? Three, is it bad to boost between 14 to 18lbs while doing the 5500rpm pulls? I am trying not to get into boost too much but it climbs way to fast.
