Engine bracket question

Sorry for all of the pictures btw I’m just trying to learn the correct things here. That’s how I have the biscuits mounted on the brackets, is that correct or not? *I know I need to remove the washers between the ears and brackets. I do indeed have 340 brackets. So I must have some orientation incorrect? Also does anyone see how the biscuit isn’t sitting quite flush on the d/s bracket, is that normal? I drilled the hole out just a tad so the dimple on the biscuit would have more room to sit into but that didn’t make too much of a difference.
