The reason is to keep the gap from closing if the piston were to hit the grd strap

If the plugs are indexed incorrectly, you will probably know after the first run down the track. That’s how I found out ......As usual , ROD BUTCHER is correct ......I always buy a ten pack of plugs....

If with 10 plug you can't get them index correctly, Moroso sells indexing washers.
Moroso 71910 - Moroso Spark Plug Indexing Washers. They have 4 different washers Bob |

Bob, the washers you have/use, are they the ones that are sort of hollow/concave?
What I mean is the ones I had were hard to "seat" ; I never really knew if my plugs were tight or not. Terry K |

two kinds of index washers avialable.... flat or tapered. flat for early heads and tapered units for taper seat style plugs...
