David,

Top marks to you on the header tank, I have dealt with the original tanks and in NZ some of the radiator repair guys used to fit a brass bolt easi-flowed (silver solder) into the center of the tank to stabilize the flex under pressure and limit fatigue! I think for reliability your tank will be great and more useable, I guess for the purist an original rebuilt tank is important to them, but with your tank painted black, and if I had an FE 427 Cobra I would have one!

My car has a Nascar Yates canted valve engine in a space frame UK Ram Cobra so I need to do a remote tank for that, or fit a high neck on the remote thermostat housing to give some water above the heads, might use a Cobra/Corvette style Harrison round tank, but I dont think you need that much water quantity if you use a recovery overflow tank!
