    Typically, most people will first choose the one that lines up with the plug hole in their single plug valve covers. Except for me, I had to choose twice.

    The holes in the valve cover are closer together than the spark plug holes in the head. This makes one tube straight and one at an angle. Use the straight tube and it will be easier installing the valve covers.
