I feed the barrel nut under the heat exchanger with some long needle nose pliers. I had one set where the studs were just bottoming out. I got some metal washers and superglued them to each side of the spacer. Gave it the extra turn that I needed to tighten it down.
I had also superglued the exhaust gasket to the head when I was installing the heat exchangers. Not a lot, just a couple drops to keep it in place. The large heat exchanger box blocks out your view and access to the ports. If you have the car on a lift, a transmission deadman is a great extra hand. Pad the metal arm. The exchanger gets heavy pretty quickly.
Get a distributor/ssi wrench for the copper nuts.
