I recently purchased a 65 coupe. The car has a 302 which is obviously not stock. The headers do not allow the last spark plug to be removed to be changed. Im thinking of replacing the headers. Does anyone know what will fit and not cost a fortune?

heed to know exactly what heads you have . . if they are gt40p heads and the old style dart windsor heads are problematic. . . hedman elite shorty's are good . . you can also but spark plugs that around 5/16" shorter if that will help.

The problem is that the back of the header covers a small part of the area that I need in order to get the socket over the plug. Im thinking if I can grind off the width of about two sheets of paper then I will have the needed clearance.

 

ok, do that then or use a thin wall socket.
