The electrical will not plug n play, they are completely different ECU's. It's probably likely that most or all if the sensor/connectors are different. The easiest thing would be to get the Engine/ECU and Harness from the donor vehicle. If the current transmission is an Auto, it may be very difficult/impossible to get the electrical to control the transmission properly. That could mean anything from not driveable to just a dash light to ignore.

Simply bolt your current heads onto the 2007 block, swap over your accessories and intake manifold and call it a day. Sell the 2007 heads for profit.
