Champion H10c is available today, and is sold as lawn mower spark plugs. Available in many if not most auto supplys, and some hardware stores. This is as close as you can get to the correct original Champion H10 plugs for Ford flatheads 1938-1953. Alan

If I read your question (title) literally, then the answer is Champion H10 TWO rib plugs. They are scarce and when you find them, expect to pay $60+ each. Your post asks perhaps a different question "What should I use..."? If "use" is your concern then go with the advice offered by Alan. If concourse points matter, start searching for H10, two rib plugs. Mike "Kube" Kubarth

If you are planning to drive your car on tour I would suggest skipping the Champion H10c lawn mower plugs and going with Autolite 216 plugs. I was 1000 miles into a new set of H10c plugs when the engine started missing going over Rainy Pass in Washington state. A new set of 216s solved the problem.

Mike is right again. Your title asks for "correct", which is not the same as "what type". The two rib plug Mike refers to is also described as having a coke bottle shape, and is priced at about $500 a set, not what you want to use for touring. The H10c plugs will have a straight shank, 5 ribs, and a silver color base. You can camouflage the base with a black dye or marker pen, but if point judged on the Concourse with a '40 Ford, the incorrect plugs will cost you points.

Thank you Don, I misspoke about the later plug's number of ribs. Correction made. Alan
