Going from the 400f to the 466f

Here in the near future I plan on boring my 400f to a 466. I had a ring snap and score up #3 pretty bad, so i figured i'd bore her up! I just wanted to ask all if anyone has any tips, or advice so that when i go ahead and do this its bulletproof. Stuff like ( clearance's installation tips, (the barrels loose there bevel after the bore making the piston installation ive heard) blah blah blah!

Share your knowledge!!!
