408 going in

I got the drivers side header in, but have not bolted it up. It is tight. Currently hitting the steering box but I have not bolted it up. I let the engine down after sitting the header in place and the header will only move about 1/8 inch in any direction. So... I will lift it up again then try bolting it up and see if that gives me the room I want once its back on the mounts.
