Offy heads use standard Flathead plugs, so they 373216 Autolite or a Champion H10 is what we recommend.

This web link referred to part number 373216 which is the Autolite spark plug for most flathead applications and is 7/16” reach, 13/16” hex, and 14mm threads. The alternate in Champion brand is 271H10. If running the Edelbrock heads the casting is thicker necessitating use of Champion 271RC12YC or Autolite number 3733924. If specific heat ranges are required you may want to check with the manufacturer of choice for availability.
