I did some more checking and there is no reason for me to try and lift the drivers side of my engine to try and install the DSE box along with the Dynatech headers. I only have a fingers amount of clearance with the transmission to the transmission tunnel.
I was over on camaros.net and found where someone else was having this same issue, but with the older designed header. Dynatech revised the header and swapped headers with this particular poster giving them the revised header. They still had slight interference, but was able to mount both together.
I suspect a distance of 3/4" to 1" of clearance would be needed for me to clear the header and the DSE box. That's too much to try and gain in dimpling the tube. The tube would be nearly collapsed at that point. I'm out of ideas with these headers and do not see how Dynatech is going to be able to make this happen. Looks like I'm gonna have to try and pull a rabbit out of the hat and make a freaking set of headers
