I believe you have a '06 Charger 5.7 yes?
if you do, the '07 gaskets are of a better quality then then 06 ones
Also use the srt 6.1 Header Bolts, they aren't expensive and wont have to worry about them vibrating out!
Above are the Part Numbers, just go to your local Dodge dealer and get them ordered
