Ballast resisters

I have a question about ballast resisters i converted my 69 318 barracuda from points to electronic ignition. I'm using the orange box and also have a chrome box available. I checked the ohms on the old ballast which measured .8 ohms but i also have a ballast that came with the kit that reads 1.2 ohms which one should i use for the electronic set up? These readings are checked with nothing hooked to the resister.
Thanks
In advance
