spark plugs

I hate to sound like a dumb ass, but i need a recommendation on spark plugs for my newly acquired 1935 Ford tudor sedan. it has worn out has Champion UD-16's, and I need to replace them, But I'm not sure what I should use. Is this the correct plug for the car? Is there something better I should be using?

 

check fordbarn for that info those guys no fords better than anybody on stuff like that

 

I'm running a 39-42 Ford flathead with Autolite 216 plugs. The Champion comparable is CHA844-1 or H10C. I find that the Autolite 216 is easier to find.

The thread for these plugs are M14 - 1.25mm X .375".

 

All your information is on this page.
Right at the bottom. While your there that forum has alot of information for flathead fans.

Second on the Autolite 216s. I've had trouble with the new champion H10 plugs, but if you can find an old set they work well too.

 

Sorry... this is assuming you have a stock flathead in your '35

 

Yea, it's a stocker. thanks everyone for your input.
