So Eagle head it Is. was just reading on the LX forums that one can swap those on. Should I decided to actually put these into something.
Right now, they can sit in the corner with the others.
But let me ask this. My 07 Durango 5.7, is this something I need to be watching for in it?
Yep. Make sure to idle for at least 10 mins after getting off of driving at cruising speeds to let the head temperature equalize before shutting the engine off. Better yet, get a Diablo Sport tuner and shut the MDS off.
