What spark plugs for 340

I run Autolite 65’s, they are cheap, work and I don’t care changing them like underwear. Whenever I go to the parts store I tell them I will take all they have. I think I have done it enough that the store computer has upped the “quantity to stock” in that store. :)
I run them in the Nopar and the Harley. Less fouling from over carbed and cammed fun
