It's too good of a deal.. for $699 to the door you can't have machine work done on your factory heads for that much... If I had the coin I'd buy a set just to have them... $58 for the stud kit that's a no-brainer..
@j par, IIRC you are running these SM loaded heads on your Duster with a solid cam? They only show for a hydraulic cam in their ad. Inquiring minds want to know...
