Ya I have those summit racing headers on my car they worked ok they clearence dosent work very well with the torsion bar set up and they hit random parts of the body/suspension worked good on my 318 but now that the 360 is in I will be buying new headers my dad is looking at these for his 340 duster http://www.jegs.com/i/Hedman/500/78500/10002/-1
