The headers look awesome. What size tube and collector did you use? Want to make another set?? Lol that's what's keeping me from installing a gen3 hemi in my 65 valant. I am not a fab guy and nobody makes off the shelf headers for my car. I just bought a 21 ScatPack challenger and for as big a car as it is. The car runs damn good. The 6.4 hemi ought to be a blast in the lighter valant.
