Re: 2010 5.7 cylinder head differences...(see also: exhaust headers)
Welcome to the forum.
The Eagle heads have the same port design as the 6.1's and 6.1 headers should bolt right on. As with any exhaust manifold work on a WK, it's a real tight fit though. I believe only aftermarket headers available are long tube headers for the 6.1, and I understand some have had problems with the rear O2 Sensors with this set up. Don't know for sure if it's true though. If you use stock SRT exhaust manifolds, you may have the same clearance issues with the transmission case (bell housing) that folks have found with the early Hemi's that use the 545RFE transmission.
