What spark plugs do yall run in double hump heads? These have to be the big plugs. Autolite or AC Delco?

Last year we ran autolites, I don't remember the part number off the top of my head but can get it later if you want.

I run the atuolite 353. These are the big plugs. same as the champion J4C. You could also use the 291 and 303 but they may be to cold. Deed

Most guys here run the Autolite 353. The 303 is actually a hotter not colder plug.Autolites are getting hard to get in this part of the country because of corporate "Can't sell a thousand a week" attitude

I thought the 353 Autolites were mainly for use with alcohol engines
