Re: Spark Plug Query
Your pictures show the head seat area very dirty, however it look like both of them is taper. Can you clean it up a little better and see if they match one of the pictures?
Looking at my pictures (of my spare heads) the long reach has a squared off seat. The short reach has a taper seat.
