Hey, has anyone installed Edelbrock heads on their 51 239 flathead engine? If so what sparkplugs did you use? It looks to me that the stock ones that were in my old heads will be a little short.
"Important Notes: Flathead head copper gaskets for 1939-48 use Victor #3036; or Fel-ProŽ #7548; for 1949-53 use Fel-Pro #1055 and Fel-Pro #1056. Recommended spark plugs are Champion RC12YC or equivalent 14mm x 3/4" reach with flat gasket seat. (Champion RC12YC)."
