Don't put them on if they are just stock castings. The 6.0's have a 72cc combustion chamber which will lower your compression way down into the 9's. You would probablly loose hp if anything. If they were milled, and bigger valves were installed I could see a gain, but stock for stock, you will loose.

you'd have to mill .030 to get back to stock compression. assuming a stock gasket.

You would deffinatlly need to mill them .030, install bigger valves w/valve job, and have the bowls blended into the new valve. Even then the gains would not be signifigant enough to warrant swapping heads. If you got them ported along with the other stuff, then yea, I'd do it, but stock for stock, no way.
