Alright Im just a little confused on these part numbers for the Eagle head. I worked on a 07 truck with a 5.7 hemi and the part numbers on them heads were 53021608de and 53021609de which is what was said at the beginning of the post as Eagle heads BUT I didnt think that they were built til 09. So when I go to the dealer what part number should I be telling them for the Eagle heads? Sixpackgut what part numbers are yours? THANKS!
