I have 1 spark plug that is closer than the rest, and if I put that sleeve on, the sleeve would be in contact with the header. I think I need very short 90^ boots or shorter spark plugs ( if they even make them). Right now I had to put Red RTV on the the one boot because the previous owner let touch and it melted thru. I also thought about bending in the wall of that header tube, just slightly.
