06 and 07. You are right, the drain back hole would have to be drilled. The problem I see is closing the other hole since the head gasket is dead center. Plugged and milled flat. Plug one and drill another or make headers, not sure what would be easier for most people. At least with headers they can be placed in the best spot. Thank you Chrysler.
The water hole would need grinding too.
