Complete Motor with headers.

I personally would recommend headers from TTI (Link) http://www.ttiexhaust.com/
Yes they cost more but well worth it. They were a breeze to put in. I had gotten a few scratches on them by 'dry fitting' them (seeing where they will hit, if at all, any problem areas to encounter, if any......) than when actually putting them on. We placed them into the compartment then lowered the motor in..........they fit like a glove. No problems with the install on my 73 Duster......No regrets with the extra money spent. TTI are made for Mopars only!!
Just my 2¢ worth.
