You are already setup for RB so I would go RB. The advantages of going B are negated by the hassles (and expense) of buying new parts. The strokers have so much more power. You hate to pay the same money to build a 440, unless you are happy with that combo, power, et etc. If it was me I'd go 512 but it's not me it's you.
