Just in case you happen upon some new old stock, here's some of the older numbers: Champion; #7, #C-7, & #D-16.       AC; #86 or C86.      Bosch; #M95T5   and Autolite;  #BT8

Sometimes hotter plugs can help in performance and/or burning off that excess oil that may be fouling the plugs. However, the late Dutch Kern found that using hot plugs can result in cracks developing between the two valve seats. His recommendation was to set the plugs at .035 which he said increased fuel mileage and cleaner burning. Just a thought and suggestion from the past!
