Most importantly, which one won't have spark plugs that cost $600 to change? I looked at a 6.2L SD today and the plug and coil is very similar to my 5.4. If they use the same plugs it is a no go.

I read in one of the articles that the 6.2l will have 2 spark plugs per cylinder to help increase fuel efficiency.

I doubt it's a 2 piece with sleeve - it's a lot more likely it's similar to the current 3v design. Remember, they redesigned the heads in mid 08 and I'm pretty confident they learned from their mistake.
