I completed my installations of the Hedman headers 66104 without too much issue ... they fit pretty darn good. They replaced an older rusty set of hedman headers with the old type flanges. Now I am installing the cut outs, of course they are stainless and my exist is mild steel and of course they line up with the crossmember making it harder to do trans rebuilds. Yes I break it every so often when I race/drive. Before I burn this all in I would like to get you all to offer opinions on how it is going. I have v'band clamps so I can remove the cutouts so I can remove the trans as well as give me the ability to clock the cutouts as needed. Nothing touches medal, this is from the front: Here is where the motor is getting tucked: This is the side view from the drivers side: Here is the crossmember and the clocked motor: This is looking from the passenger side straight across to the drivers side: This is how it looks from the rear: Here is the cut out dumpers: What do you think?
