My shop manual originally calls for Champion spark plug H-8 with a .035 gap. I found the cross reference to Champion stock#587, part#H8C. However, I think I may have gapped them at .030. I could swear I saw something for that plug and my V8 saying to gap them there instead of .035. Anyone know for sure which gap might be correct?
