I had the same issues.
1) Grind down the header to clear the temp sensor. Just a bit will do.
2) Cut down the bridge so it clamps to the flange rather than the step.
3) Every bridge will have to be ground on one side. The two flanges are different thicknesses. I had to do it as well. Measure the flange thicknesses and grind down one side the amount different. It'll tilt a bit to help take up slack. Washers are fine and all but the bridge can be made to work better if you grind it.
4) Don't use studs that are too long on the front bridge if you have power steering. If the stud is too long you'll run into interference issues with the steering pump bracket and pump.
5) Get a can of VHT and re-shoot it when you're done. Follow the bake-in procedure on the can and it'll hold up very well.
