OK I went out and purchased new plugs for my slant. I picked up NGK ZFR5N's and so now when I compared them to my old plugs they are about 1/2" longer then the old ones and in this forum it is said to cut off the gasket I just want to make susre that I dont tear anything up before I get started. This is going in my 67 slant it has the spark plug sleeves.
So someone please let me know I not screwing this up.
